Driveshaft question

[dirtracer_75]

Going from a ball spline to a standard bert. Besides needing a yoke, will the existing driveshaft work or is it a different length?

Most mods with a Bert, take a 31 1/2 inch DS

2" shorter with an 8" long front yoke. Make sure the yoke will slide all the way into the tranny. If it doesnt, you will have to change tailshafts or get the tailshaft undercut in front of the splines. There has to be at least 2" of the yoke inside the rear seal at ride height or you will loose the driveshaft.

Heavy duty, what should the drive shaft length be with a ball spline? Standard 108 inch wheelbase car. Thanks!

Guys are running a 33 1/2 or 34 in our cars.
