use the gear boxes from a VW bus they are enclosed units

I don't really know much about VW's bubbajoexxx. I'll have to do a little research on that for sure.
Spent some time today working on notching the upper frame rails, similar to what Blooz has already completed. This is necessary as the finished car will be much lower and even though the track has been widened, the inner edge of the tire is going to impinge on the space occupied by the upper frame rail. My goal is to have 3 1/2" of clearance which should be enough as I'll only have a maximum suspension travel of 3". I started with the drivers side and once I marked out the arc through the rail, it was a quick cut with the jigsaw. I decided to notch the frame rail completely though to the inside surface as I wanted to remove the inner flange in an effort to ensure my strut had plenty of room in it's new wide track position. Once cut, I basically capped the notch on the bottom as well as the inside and outside faces of the upper frame rail with 1/8" plate. I extended the inner surface upward enough to form the surface that the new strut tower will be fastened to. It's all just tacked together at this time.
Here are a few drawings of the arrangement.
And here are a couple pictures of the drivers side cut out and the new pieces fitted in place and tacked together.

What is the gear ratio of the units in the upper two pictures? If they are 1:1 then they are exactly what I was thinking of. Any idea what torque they can handle?

They look like the casing is slightly oblong, similar to the bottom picture which appears to have a 1 : 1.25 ratio ( depending on which is the input shaft )

yes and if you use them correctly it will give you a final drive of 3.35 to 1

Holy crap Graham... I had to bump your thread up from something like #25! At least I have a legitimate excuse for being #24 (and now taking your former place at #25). What's going on in Yarmouth?

Hey Blooz. I've been busy working on the notch and reinforcement of the upper passenger side frame rail as well as finalizing some design work for the new strut towers. I've also been doing some design work around the LS1 and Audi gearbox as well as working out the basic design for the new engine cradle. On a positive note, I ran my dual drive belt design by a close engineer friend who builds dragsters and he thinks the idea has merit ( assuming the belts do what they claim ) 
To be honest, I have been a little hesitant to post any progress updates knowing you were home laid up in bed for a few months, unable to get out in your shop.
