Replacement Differential

I have to replace the Dana 36 differential in my 84. I'm thinking of getting it from Zip. I've considered others but the price seems very reasonable and they give a 12 month warranty.

Does any one have experience with differentials from Zip? I'm looking for the Good, the Bad, and the Ugly before finalizing my purchase.

Dana 36 diffs are a dime a dozen. Check the for sale section. You should be able to pick up good one for a few hundred.

Don't know if it will fit but I have a 2:59 pumpkin out of my 92 you could purchase.

If you were in Norcal, I've got 2 places for you. You are on the other side of the world though.

Is the ZIP unit just "refreshed" with bearings and maybe a clutch pack or is it a new R&P install with appropriate bearings etc?
