Is the rear end still for sale? If so I have some questions:
What kind of modifications would be needed for installing in '63 vette?
What does OJ mean?
Is this a posi-traction unit?

you will need to replace the rear u-joint in your driveshaft with a combination u-joint.
"OJ" is the GM designation for a 3.7 from a 1979 Corvette.
yes it is a positraction

OK thanks for response. Not sure what problems, if any, a combination u-joint would create. This unit would be going in a '63 vette with a Tremec 5 speed and 500hp plus engine. I'll keep looking.

a combination u-joint only means the cross is longer one way than the other and guys have been using them forever, it`s no big deal, it allows you to use your existing driveshaft with a larger or smaller pinion yoke or trans yoke.
