I recently replaced my 4x4 4L60E with a 2wd one on my 99 Chevy 1500 ext cab long bed , everything fits perfect except when I got to the drive shaft part I tried like 3 different drive shafts and all of them seem to not work and be in the way of the torsion bar.. anyone has did a conversion like this or does anyone have ideas on what I should do ? yes i have tried a 2wd 2 piece driveshaft.
