What rear-end is this?

I have been looking at CJ-7's and have noticed a rear diff that I have no idea what it is by looking at the diff cover. The cover is perfectly round and is bolted down by torx bolts. Is this the AMC 20 rear-end or an odd Dana 35?
Thanks in advance. :screwy: :banghead:

Sounds like a 20. Which were pretty comen in the CJs.

Yup and check this page out, tells you all about the shapes.

Thanks guys, now one other question, when lifting a Cj with the AMC20 rearend, is it stong enough to handle 32-34" tires or should I look at changing it for the dana 44?

Do a Dana 44 or a Ford 8.8 off a Explorer 1995+
