Dana 20 to Dana 300 swap in a CJ-7
 

Group,

Has anyone done this? I know I will have to get a different adapter to mate
the 300 to the GM TH350 auto, but what about the driveshafts? Will I have to
deal with changing the length? What else?

I am doing this not because the Dana 20 is bad or weak, but because the 300
has a 2.62:1 low range, and I can probably do this for less $ than going to
teralow gears. I can go to a twin stick as well.

Thanks,

RR

I bought it already converted, but I would imagine that it came with a 6 /
manual, and the other owner kept the D20.

I don't believe the Dana 20 was used in the seven:

Bill,

I am not sure as well. It is a 76 CJ-7 though, and think it was, but I could
be wrong. In any event, it has a low range ratio that could be lower for my
use, and the 300 may be my best way out of the problem without spending 4
digit dollars.

Re: Dana 20 to Dana 300 swap in a CJ-7
 

My '76 CJ-7 came with the following.
258cid 6 cyl, T-150 3 spd, Dana20 Transfer case, Dana30 frt & AMC20 rear.
I swapped in the T176 4 spd w/Dana300. It was a direct fit but needed a new
front driveshaft. I think the rear driveshaft was okay (been many years
since).
