My 88 pioneer 2wd has the large driveshaft, approximately 4" in diameter. I found out that it's double walled or something.
I'm swapping in an AX-15/NP242 combo. I have seen people say they shorten down the driveshafts on the trans end, but can't shorten the axle end.
I was considering installing the sye on the NP242 so obviously I may can't use the MJ driveshaft at all. Would a XJ driveshaft strength be sufficient if it was lengthened? Since the diameter is 1.75".
