If your parts van is a "normal" US model, you'll probably not have
any difficulties. However, I discovered to my chagrin, that there are
sometimes differences. The front differential of my Tristar has a
different ratio than the transmission on my camper. Not compatible
(or rather, the viscous coupler will get a BIG workout, if you try to
mix them.)
