well mine worked i took a driveshaft from 96 man, and put it in my auto, it was a half inch shorter. Thanks for the help
it's almost exactly 1 inch. If your suspension travels all the way in the front and that shaft bottoms out, it's going to break something. The rear is not as big of a deal though the more spline engagement the better. At a minimum I would shorten that front. It only cost me $45 to have the front one done.
I think the manual front driveshaft is shorter, than an auto.
the frt drive shaft in the manual is shorter and the rear is longer
