I got the Ramco mirror mounts completed today. They are even more rigid that I was expecting
Too bolt things in place I needed a drill motor with drill bit that was no more than 4-3/4" long. I bought one of those angle drills in the hopes that I could chuck a bit in and get it to fit in between the frame members. No such luck. So I had to shorten a couple of drill bits that would allow the drill and bit to fit in the cavity between frame members. As you can see in the next to pictures the drill bit is kinda short
I started off by marking the frame member where I needed to drill the two holes and then used a tiny center punch as a guide. I then used the smaller of the two drill bits to bore a guide hole and then followed up with the larger drill bit.
Once the lower holes were drilled I enlarged the holes in the angle for the 1/4" bolts to pass through into the frame member.
I set the block in place with the bottom angle attached and bolted it in place. I bolted the top angle to the plate and then using a 1/8" diameter 12" long drill bit I used the small hole I had bored in the angle as a guide to drill into the upper frame member. I then followed up with a 1/4" diameter 12 long drill bit to finish up the top two bolt holes.
Next I tightened all the bolts and moved outside to install the mirror. The large hole in the center is for the power window wiring.
I made the decision to move the drivers mirror as far forward as possible to give a better viewing angle. The passenger mirror is set farther to the rear to provide clearance for the diagonal window frame.
On the drivers side I have to plug two holes with Olympic rivets. On the passenger side I'll have to plug six holes.
I'm quite happy with the installation. The mirrors are nice and rigid and located where they need to be for driver comfort.
