[quote=""Jeff V.""]Who knows? Maybe I'll try fiberglass just because I haven't done it before.
BTW, I picked up the '90 Ram 50 books (with the powertrain diag books) a couple weeks ago. I just got the '92-95 combined Mitsu book. It's got a pullout wiring diagram for the whole truck. It basically fits on 3 pages

I've got the body repair manual coming later this week.
All told, I've got about $50 wrapped up in manuals. I don't think there was anything special about 91 compared to the other years, and 96 didn't have a V6, so I should be all set on service documentation.[/quote]
Great. I got mine a couple weeks back too. If I get the 91 I will be hitting you up for the wiring diagram. When I bought mine it also came with engine specific Mopar books too. They did a much simpler job calling out the proper ecu pins. I can scan a copy if you like.
As far as i know there is no electrical difference between 91-96 other than OBDII and like you mentioned no V6 the last year. Mechanically I think the only difference was in the transmissions adding A-500 in 91, but not sure if they made any changes to it during its run. The V5MT1-1 went to -2 in 91 and may have gone on to some other internal changes, but haven't dived into it past that. Most of the upgrades were to the 1-2 syncro.
