I went the other way with my 1980 caddy. Full 1.9 n.a. diesel with big tall tires and posi in the diff. Lifted for off road use. People trip the hell out when i take it off road and never get stuck.
I had a rat eat into wiring to the dome light. It grounded my battery to the body and swiftly drained the battery at .03 volts. I ended up fixing it, after having to undo some of the headliner I had just installed.
