Dusty, you asked for dimension, maybe these will help; the spreader bar is sitting on the body mount part of the forging and the forward face is centered over the body mount fastener hole:

The blue line (rounded off dimensionally) is 10". The red line rounded off is 7 3/4".

Actually I was asking for dimensions of the body shell, Lee.

And don't go running off on account of me. Like you, I like to teach what I have learned. And I know far better than most (especially most of those who have purported to be my teachers) that there are a million ways to skin a cat, in this case, that cat being a fiberglass body buggy. And I also know VERY WELL that many of those million ways will work just fine. Don't think I'm telling you that you are "wrong". I'm suggesting another way than what you have in your mind is all.

Not sure what dimensions you are looking for. The body is a bit different in the rear so I have to do some FG work on that. Again, this was taken when I had a Cologne V6 in it that was tied to an 091.

Other than that the lower body ends at the back of the pan which is a bit in front of the rear wheel fenders. This is an old picture but is gives you an idea of the rear of the buggy.
This is that upper tray I have been talking about. You can see the capped opening in the tray that I added where the fuel tank inlet would bee; open up the cover and the fuel tank cap is intended to be just below that leve.
Again, an old picture but the end of the transaxle is just a bit inside and below the Horseshoe cut out in the back of the body.
This is when I had a V6 in it but it should give you an idea of where the end of the pickle forks are in ralationship to the body.

There is plenty of room as long as it is used wisely.

Does this help?

Dusty asked me a question a while back that I didn't answer as it was kind of complicated and I didn't have measurements. That question was how much room did I have in the new Truss/Kaffer bar design to the drive axle I was working on.

Ok, this is the buggy with trans and no engine or passengers. The trans is a stock bug transaxle with drive flanges that will be able to use a Type II or 924/944 CV joint. The spring plate is notched 1/4" and, as you see it here, the revised preload on the torsion of 24° (I think that is what I set it at but it was so long ago) so the spring plates, as the picture shows, is sitting on the stops.

The tires shown here are 30" dia. which is the same dia. as the Desert Tracs I will be running. I will keep the stock bump stops so that even with some compression on a hard hit I should be OK keeping the tires and the fenders apart. The max angle of the Bus CV joint is something like 17° but in the following pictures the axle angle is ~20 degrees. I have been using a similar setup (091 trans and bus CVs) for many years not so I think I am OK

I just took these today.

This is a 1 X 2 rectangular tube for the spreader and I was using a piece of 1" square tubing to get some measurements between the bottom of the tube and the rubber boot. The measurement in all three pictures it to the second rib of the CV boot.

In this setup I have a ~ 2 finger clearance at full hand. That comes out to about 1 1/2"s. The measurement is going to be off a bit due to the measuring of an over sized square tube as there would probably be some additional room when compared to a round smaller dia. tube for the clevises'.

By moving the connection to the spreader up higher on the rectangular tube I get a ~2" clearance.
IMG_1097 copy.jpg
By going back to the 1 X 3 rectangular tube I get ~2 1/2" of clearance at full droop. I didn't have anything long enough to get a good measurement so I used some string. This makes the measurement a bit off but close enough for an idea of what is going on.

I haven't pulled the torsion bar out to see what full compression will do but that will have to be done before too long... before I go and get a chunk of 1/8" wall rectangular tube... most likely 1 X 3. Being that the measurement to the boot was so close to the CV I am not sure just how much of gap to the axle to expect on full compression. Being that the axle is traveling in two arcs simultaneously is going to be interesting.

I might be able to accomplish it without pulling the torsion bar by using the tool for setting the preload; don't know yet. Too tired from what has been going on here for the last few weeks.

Anyway, part of the answer (I hope) to Dusty's question.
