67 gto driveshaft with 12 bolt rear and th400
 

I have a 67 GTO with TH400 and 12 bolt Chevy rear. I've seen driveshafts for 66-67 chevelle, th400 to 12 bolt rear, will it fit?

Yes.

Both cars ride on essentially the same chassis.

Transmission placement in the frame is the same for Pontiac and Chevy, so the driveshaft length is the same as well when using the Chevy 12-bolt rear.

With a conversion U-joint your original driveshaft will fit.

You may use Chevelle, Cutlass, Skylark as well. Any GM A body of the correct years from your local junk yard should have a nice selection.

Thanks guys.. My orginal driveshaft which was the correct one was sheared off when my transmission grenaded. :-), so I need to replace it with a complete new one along with a new TH400 and who knows what else once I get the car apart to see the real damage. I'll post some pics later for your viewing pleasure. :-)
