my bad i didnt write in the details of the swap. and i got a little bit wrong. I haven't asked him yet but I believe it was actually a CJ-6 2wd 225 slant 6,904 tranny,3.73 gears. it had a bunch of dodge pickup stuff on it so probably the dodge rearend. but he swears up and down it got steady 20+mpg back and forth to work @ 55-60mph.
