Well, well, well. After all that measuring and fiddling around with the stub shafts, wheel bearings, caliper mounts, etc. I measured up my driveshafts CV end to CV end and compared that to the gearbox output flange to stub shaft flange distance and WALL AH!!!!!. Exactly the same to within a 1/8 of a inch. 23 inches at normal ride height. This was one of my primary goals, to not need to replace the driveshafts and still change over to C7 type bearings. I did need to alter the caliper mounts and rotor position at the rear but that was pretty cheap to do.
So that means that I don't need to change the driveshaft length and can reuse what I have. Friggin perfect! Merry Christmas to Me! Now back to the fronts and to install the spherical bearing retro fit kit.
I will come up with a summery with part numbers and vendor information along with a total cost when I have the car completely back together. This has been quite a evolution to retrofit my original non race suspension to C7 type bearings but I think this is the right thing to do. At least for me.
