Yes, I have tried the 4 door tank in a 2 door. It fits. Yes I am trying to put a 4 door tank in a lwb sammy....gonna make it work.
I've been driving a 95 4 door around, including low speed wheeling, for about a month and a half now. It lugs just fine and has plenty of power for the freeway. With a bad TPS, that is unplugged, it still gets 25 mpg on the freeway and about the same in town.
My lwb has a built 8v 1.6 in it, the 16v I think still does a better job lugging. Just my opinion.
