I have a TH350 going behind a 348 3X2BC engine which is a long output shaft type which is 3" longer than the prreviously fitted later alloy PowerGlide.
So now I need to shorten the driveshaft, so today I removed it but I noticed something strange.
Normally the driveshaft universal joint yokes are inline, that is both ends at the same angle. I realize that the universal joint in front of the mid bearing is on a spline, but moving from spline to spline still wont align it.
I noticed the yoke has a missing spline, so thought that must align it, but the splines on the male part of the shaft have no corresponding part, so the yoke will locate on each spline.
The car had previously been fitted with a late PowerGlide so wondered if the driveshaft had already been shortened and welded rotationally incorrect.
Can someone check and prove the rotational alignment of the yoke and the center to center distance of the first driveshaft section please?
