ihave a nv4500 mated to a 205 that will be coming out of my chev to put in the dodge nv4500 and 205 when i put in the diesel. my question regards shift covers. the chev has a 2piece and the dodge has 1 piece. i was wondering which is better and why? are they interchange able? seems to me i saw a post saying the 2 piece was better shifting??maybe?i don't see why they can't interchange, but it has been a while since i have had the chev apart.
