74 power wagon dream truck...

205.. no chain...
The front drive line doesn't even move. And the rear drive line could be the culprit and I'm going to shim it and check that...
Oh that’s right. 205 Divorced transfer case. What I’ve noticed with mine was my transfer case shifter bracket that bolts to the trans crossmember…. The bolt holes are slotted, allowing adjustment of the shifter bracket location. Mine would hang up a little, and not like to shift, I loosened the bracket and readjusted the position.
