You have a good point about those 1/4" screws. I don't know how many bent bumpers I've seen that still had the bolts intact! Heck there's an Argosy sitting in my driveway right now with two bent bumpers and no broken screws!

Last Wednesday I ordered what's called a Reverse Thread Chasing Tool to repair the damaged spindle threads. The tool arrived last night and worked very well at repairing the threads.

From past experience it seems that when threads get damaged it's usually at the end of the bolt or threads and you can't get the thread chasing tool threaded on properly so getting the threads repaired is a real challenge.

The thread chaser that I ordered is split so you can clamp it on to some good threads and then back it into the damaged threads. I used a C-clamp to keep the chaser closed and the clamp also served as a handle to rotate the chaser. It took all of about 15 minutes to repair the threads.

Needless to say I'm quite happy with the results and I now have the front hubs/rotors installed and believe it or not this is the first time since I've owned the Argosy (2007) that it has had front shocks installed

That is a neat gadget Brad, in searching for it I don't suppose you come across them being loaned/rented by any of the auto-part stores?

This is the only thread chaser I found that would work on the odd spindle threads. Considering the unique thread size I would be surprised if any store had something like this available for loan.

I had never heard of a thread chaser that clamps on like this one does. I was initially skeptical about how it would work since it's a 2-piece affair but once it arrived I found it to be very well made and very precise.

The spindle threads are 27/32"x20 which is an odd thread size to say the least. I really wasn't expecting to find any thread chaser so when I found this one I had to give it a try. $50 wasn't cheap for a one time (hopefully!) use but my options were pretty well limited. I suppose I could have used a 20 thread per inch file but I've found those to be a pain to use.

Bottom line is I'm pleased with the tool and pleased with the results.

Not a lot has been happening on my Argosy for a while. Between traveling to the Get Together, constant mowing and tinkering with Peanut I've been somewhat busy!

I did find time to try and install the front brake calipers and found that I was missing the wedge keys that hold the calipers in place. By coincidence while at the Get Together Matt gave me the front knuckle, rotor and caliper assemblies from an early 80s P30 chassis that just happened to have the wedge keys

I like it when a problem shows up and gets resolved immediately with no real effort on my part

I did run across one rather annoying issue while trying to install the front brake hoses. The mounting tabs on the frame where the hose and hard brake line meet have round holes for the hose to fit into. The replacement hoses have a hex shape to them and don't quite fit into the holes

I think the best option is to take a file to the holes and create the hex shape for the hoses to fit properly. It's annoying little issues like this that continually crop up causing delay after delay. Oh well....

While at the fab shop picking up the generator floor for Peanut I asked to see how they were coming on my replacement gas tank.

The cutout on the lower left is required to clear the rear leaf spring hanger. Assuming my calculations are correct the tank should hold a little over 50 gallons when full.

They might have the tank done in a week or so at which point I'lltake it straight to the local radiator shop to have them seal the inside to help keep the rust at bay.

The caliper and brake hose installation is done and I've since been plugging away at small tasks related to the brake and hydroboost and the associated piping. Hydroboost and brake MC are installed and I also took the time to pull the new power steering gearbox for painting and it is reinstalled as well. I also took the opportunity to add a power steering suction line filter similar to the one Dean installed in his coach.

When the old hydroboost piping was removed one of the fittings between the hydroboost and a brass T was frozen and the pipe twisted off during removal. It took me several hours of googling on Saturday to find what I hope is the right size replacement fitting. The new fitting won't be here for a week or so and needless to say I'm really hoping it's the right fitting!

According to GM the boots have been discontinued. I've looked for boots that are similar that I could modify to fit with no luck. If you've got a suggestion as to what might work as a replacement I'd love to hear about it!

The rough dimensions are 8" long, 2" at the top and 5/8" on the shaft itself.

Thanks!

Brad

Maybe worth searching for a motorcycle fork gator Brad, I am sure you will get the length and width at the top, but you may have to wrap the shaft to pack out to a more standard 1" size.

Martin, that's a great tip!

For a grand total of $7.85 I ordered a pair of these Universal fork boots shipping from China. If I can't make one work at least I'm not out a whole lot of money!

Well that was fun. I'd been putting off torquing the large control arm nuts on the front suspension for too long and decided it was time to complete that task. The lower nuts had to be torqued to 280 ft/lbs and the uppers to 190 ft/lbs. The problem torquing the upper nuts was socket access for the two nuts close to the brake hose brackets. I couldn't get a 1-3/8" socket and torque wrench on the nut, not enough clearance. I finally tried using my 1-3/8" crows foot and problem solved!

The difficulty on the lower control arm nuts was I don't have a click-bar type torque wrench that will go to 280 ft/lbs. I have a Snap-On 3/4" torque wrench good for 600 ft/bs but it's a dial type and I wasn't sure I could read the gauge and apply pressure at the same time.

With careful placement of a light and a mat I was able to position myself so I could just see the dial. It helped that I marked the 280 spot with a Sharpie. Torquing those 8 nuts officially completes the front suspension rebuild

I've got a short list of about half dozen items to wrap up and I'll be ready to install the engine in the chassis. That's probably about four to six weeks away at best.

Thanks! What's really nice is installing all this stuff and not getting dirty and greasy in the process

The other day I was looking at some of the pictures I have of Martin's Bella and realized there were several differences in the lower rear quarter panels.

Mine has a storage compartment with hatch cover located at each rear corner. I've known for a long time that my argosy seems to be the only one equiped with this feature. What I noticed recently was Bella doesn't have the reflector pad that mine has.

My plan is to remove the reflector and add a marker/blinker light in it's place.

I still find it interesting that my 74 has so many differences compared to the 75 and later models.

Lately I've been pushing to get the front area of the coach done so I can install the motor. Some time ago I reworked the doghouse opening to use the doghouse I salvaged from the 345. There were a couple of items that needed to be wrapped up to officially say the doghouse opening was complete. I had to add gussets to the rear corners of the opening to cover the gap created by the rounded doghouse cover. The main reason this needed to be done before the motor install was due to the welding required to install the gussets. I didn't like the idea of welding above a fresh motor

The last area of the doghouse opening I needed to complete was the firewall opening. The shape of the 345 doghouse is different than the original Argosy opening so I had to adapt the firewall section from the 345 so it would fit the Argosy. You can see in these two pictures the original opening is rectangular.

The 345 opening is shaped to match the doghouse cover so I had to fabricate a plate and add some 1" square tubing to get the shape just right.

The last major task left in the engine compartment area is to use some black vulkem to seal all the seams. GM used some sort of black tar like substance and I think black vulkem will work just as well.

I should be doing a test run with the TBI installed in about two weeks. Once that's complete the engine is going to be set in the chassis
