    I think it really depends... I put on a 4 inch susp lift on my 78 and I had my driveshaft literally fall out 2 times... when I lock up the rear brakes the body flexed enough to make it happen... So you may have to... not everyone has had to... I am addin gmy 3 inch body lift saturday and it shouldnt make a difference in the angles.. it ha nothing to do with the drivelines (the body lift)
    SO... You may need to./.. if you do the lift and can see the splines on the rear one... you better do it.. or your asking for trouble... mine had 1/2 inch showin of the spline... I had the shaft lengthened 1.75 inches...
    Cost me 140... Installed and painted...

    Um... yes officer I know it's too big...
