We have a winner...Ed.  It's a 1993 Corvette I.R.S. complete hub to hub.  Plan is to slide it under the '39 but there are a few problems.  Got to narrow the unit by about 5 inches, make new adjustable mounting arms (8) and new frame rails.  Oh, and plan to air bag it also.  Gears will have to be changed from the present 2.73 to something like 3.31.  Fun project!

trick with the corvette is the rear bridge mounted between your frame rails. 

The aluminum half shafts should be done by driveline drive shaft specialist..

The 2 bolt holes on front of top of pinion on the case are the pinion snubber.

The sway torsion bar in rear cannot be narrowed,  a custom one will have to be made by ???

Just getting it apart was like Joe vs the volcano!  Still have not attacked the axle nuts and bearing hub.  Did order a 36mm socket for the axle nut and T55 torx for the bearing hub.  When building the car I drew up plans and built a new frame and still have the plans so what I intend to do is build a back half on the bench, cut the old back half off and weld the new one in.  I'm to old to crawl under a car to build the whole thing.  Already have the new back half rails built so it's just a case of finding the width that fits the 'Vette rear best and go from there. 

By the way, the sway bar CAN be narrowed.  Did it on my '33 Willys, worked perfect, put over 30K miles on it and some duty at the drags.

I learn something new everyday, did not think was possible.

My 33 Willys would lift one front wheel on hard starts and the body roll was bad too because of the narrow wheel width.  Went to the junkyard and found a T'bird sway bar that didn't have a bunch of bends in it.  Cut a bunch out of the center, V ground the ends and welded back together.  Forgot to put a sleeve on before I started but figured if it worked I would build a better one.  Car launched flat and true after that and cornering was wonderful.  To this day the proto is still under the car and working fine.  I'm in touch with a guy building a carbon fiber '37 Chevy coupe and to solve his sway bar problem in the back he's using a Paul Horton Weld it series adjustable bar. 

Golf and cookout got in the way today.  Will attack again tomorrow to get the axle nuts off.  Once I have the knuckles off I'll take the center section and knuckles to the sand blaster.  Center is sealed so on sand SHOULD get in but will be disassembled for a gear change anyway.  Nice to work with clean stuff.

My approach to narrowing the sway bar is admittedly bonehead engineering.  Had to start somewhere and a little research indicated that most sway bars are not some exotic spring steel.  Not sure how much torque is on the bar, anyone know or educated guess?

Looking for a proper sealer to go onto the aluminum parts after sandblasting.  Don't know if a clear coat will stick and/or peel.

Hope everyone still have ten fingers after the 4th.
