Gunter, here's a picture showing how the AC mount is attached to the front of the block.

Gunter, I neglected mention there is also one bolt on the ac mount that is behind the power steering pump. The bolt screws into the cylinder head and I think it can be removed without disturbing the ps pump. Worst case is you can loosen the ps pump and rotate it out of the way to remove the bolt.

I've been trying to get as many detailed pictures as I can of the front area of the engine so I have some reference material. Once the radiator is in place you have to work blind after that!

Talking of installing the radiator. I found a reference showing that GM 343414 (the lower radiator house which hasn't been available for some time) is actually the same as a Drayco E70735, a top hose used in other applications and available from AutoZone. From the pictures it does look similar but is always shown as used for the upper application and looks upside down. Certainly worth investigating.

What's odd is when I searched for Dayco E70735 in Google, the first item Google returned was a listing for Autozone and the listing title was "Search Results
Dayco/Hose (Lower) E70735- ReadReviews onDayco #E70735"
but when you open the link Autozine says its an Upper hose.

I'm going to pick one up in the morning and see if it will work. I don't like the generic one that is the suggested replacement. It fit's but I don't like the fit at all. I'll let you know what I find out.

The lower (water pump inlet) hose usually needs a large spring inside it to keep it from collapsing due to the pump suction. If you're getting a new hose and it's not marked as being intended for a lower hose application, then make sure you get a hose spring separately, to put inside there.

I purchased Gates replacement hoses form the local O'Reilly' store. The upper is a molded hose for the 454. By cutting a little off at thermostat housing it fit as well as the OEM Chevy Hose. The lower hose is no longer available. I have one that is over 20 years old and don't trust it. (I keep it as a guide for replacements). The Gates lower universal fit hose has the spring molded into it and with a little twist and a plastic tie wrap fits quite well.

Well to put it bluntly, the E70735 hose will not work as a lower radiator hose for the vertical radiator rigs. Not even close

However, I'm fairly certain it will work as the upper hose which is how Autozone advertises it. I couldn't quite get it next to the hose that is installed on Peanut but after looking it over I think it will work. I should be installing my radiator in a few months at which time I'll give it a try. Due to the various curves it may have trouble with some engine configurations.

Not sure why the Winnebago crowd lists this as fitting a Winnebago unless there is something radically different about them compared to the P30 chassis Airstreams and Argosies.

Sorry for the bad steer Brad, but I think it was worth a try.

No bit deal. If it works as an upper hose I'll be happy. If not I can return it as long as its never been installed.

It's always worth while checking out leads for replacement parts!

I guess there is still the option of the Bronco hose Greg found in this thread?
