if you have a large enough sway bar 15/16 ---1" your not going to get any body roll into the quarter panels wheel wells.

Well here it is with the rims on.  Outside to outside of the rims is 68 inches and I THINK that there is 70" fender to fender.  Would really like to narrow 1 inch on each side to ensure room for tire bulge and the fender skirts.  Still have to build the dog bones and then it's just wait for cold weather to take the car down for the install.  As much as I've tried to think of everything I'm sure there will be snags during the install.

Had a bright idea last night compliments of Canadian Mist!  Why not get the tires that I want and mount them on the rims and put them on the car as it sits now (with the 8.8)?  Measure the hub to hub on the 8.8 and the 'Vette,  add the difference to the tires once mounted and see if they fit.  Actually seeing the fit is much better than "in theory they should fit".

Lol   I got a kick out of your post.  :D  Dad use to tell me " Slow down...your way over thinking this"  ;D

Friend of mine years ago did as you are in rear end install, only with a C3 set up. ('70 Chevy short bed) I would check on it ever couple days when I was in town. Really hurt my brain looking at all the angles and degrees he had skeched down for all the mount points.

When I was trying to figure out how to do my '34,  I had to remember what the 'ol man had said. Got the tape out and realized ... hell the C3 Vette rear frame would just fit as is. Bobbed it off complete and welded it on.   No brain explosion at all! ;D

Great job your doing on yours, sure looks good. Way above my pay grade!

Talk about crash and burn!  Did anyone notice my last post about putting the new tires on the Camaro rims and mounting them on the 8.8 axle?  I got all the way to the car and was about to lift the tire onto the studs when it hit me...Ford axle, GM rim, ain't going to fit.  Well, it went downhill from there.  Nice to have all the parts in one place and was able to do some accurate measuring.  Tires outside to outside mounted on the C4 mockup is 69 inches.  Inside fender to fender is 70 inches.  In my mind this is to close which means narrowing the half shafts 1" on each side.  Getting the mock up on the floor, leveling it and measuring frame to ground I think I'm about (at least) two inches to high.  To lower the car I can move the pumpkin up to the floorboard which is 5.5 inches.  This will require major mods to the frame rails.  I'm going out in the garage now, drink a few brews and wait for a flash of brilliance.

I'm sorry 39delux. It's easy for me to say but, back to the drawing board. By the looks of your work there is no question that you'll figure it out, that's for sure.
Tighten it up til it strips, then back it off a quarter turn

Sometimes a few brews and staring at it for an hour or two will help ;)

whatever that bracketry on the outside of the frame is behind tire, gotta go some where else, otherwise first lean of frame and tires are toast.

You need a sway bar in the 7/8 --1" thickness to stop any body roll.  SCHROEDER makes custom splined sway bars in a width you specify.

I have a .900 thickness on my 35 chevy coupe with jag with tires 1/2" away from frame, per side with no problems.

Gathering all the parts and about read to start the real swap.  Bat wing needs to be narrowed by 1" as well as the half shafts.  This means the Strut Rods need to be shortened too.  They are at the machine shop/welder now.  For a little more safety I am building wooden stands for the front wheels.  Think they will be a little more stable while removing the rear end and shaking the car a bunch.

And so it begins, got it up in the air and starting to strip everything.  All went well 'till I upended the gas tank and found out my gas gauge is off just a bit.  Though I had a little less than 1/4 tank but it spilled a couple of gallons when it landed and still dumped out about 8 more!  More planning, drawing lines on the floor and frame to locate the pumpkin.  Cooler weather in the AM and golf may get in the way.

very nice soft white pearl tone paint.  Tail lights really suit the body design.  Fulton style sun visor really suits this body style

Reaching the point of no return.  Cut the floor pan out to get access to the upper bag mounts.  They are directly in the way for a cross member to support the pumpkin.  Took three days to clear everything around the rear part of the frame.  Right now it looks like I will NOT have to tub the wells.  Time will tell.  Next up is positioning the pumpkin which will dictate the ride height.  Measure twice and cut once or in my case measure with a micrometer, mark with chalk and cut with an axe.

Looks like things are out of the way and it's time to start putting things back together.  Made a cradle for the pumpkin so that I can jockey it around and adjust the angle.  Once that is in place where I think the height should be then make and weld brackets for the nose and bat wing.  This will define the ride height and driveshaft angle.  The engine is two degrees down so the pumpkin will need to be set at two degrees up.

Moving along a little.  Got the pumpkin and bat wing mounted.  Now I have to find someone with a 200+foot pound torque wrench so that I can torque the axle nut (170).  Want to do that before setting the knuckle in place and connecting the half shafts.  Worried about where the dog bones will meet up with the frame.  May have to do major frame renovations.  The cradle that I made for the pumpkin to set in was my best friend while centering and setting the pinion angle.
