- 1980 Jeep CJ7 Project. Currently 258,SR-4,Dana 300,AMC20,Dana 30. Soon to be 258 Rebuilt, T-18A, Dana 20, not sure on diffs but regeared for rock play.
Oh and a daily driver thats a 2011 Chrysler Wrangler JK Unlimited. With the number of issues since purchase on 1/15 I can't even bring myself to call it a Jeep.
I currently am doing a body off rebuild of a 1980 CJ7 . While the body is off I am rebuilding the Engine, and want to swap the SR4 with a T18a and Dana 20 , but I am not finding a lot of help (at least that I understand).
I can rebuild engines all day long, but I normally leave the rest to the shops, but this time I want to do some of the work myself.
I have a T-18a and Dana 20 plus drive shafts from another CJ7 . I have no idea what year, but the Engine was a AMC 304 .
From what I have read, the Bell Housing will bold to my AMC 258 i6 / 4.2l fine, but after that is a bit unclear to me. The only clear difference I can find between a AMC 304 mount vs a AMC 258 i6 / 4.2l mount is the bell housing adapter to the Transmission . And references to the T18a possibly having a slight vibration in the drive shafts due to the angle to the differentials. And possibly the shifter needing heated and rebent.
Can anyone tell me what else I am in for?
My plans are to put a 4" suspention lift, and a 2-3" Body lift in, as well as to regear the differentials and install ARB Lockers. I'm going to do all this work while the body is off to make life a bit easier for me. I haven't totally decided on the differentials yet, I may be changing them out, not totally sure yet.
One thing is for sure though and that is that the SR4 has to go.
