looking for an open small case diff, I dont care what the ratio is, just looking for something cheap. Thanks

I think they're all the same - even between open and LSD diffs. You'll need the small case ones, I'd suspect.
Mine are all really rusty too, but the seals hold & the bolts are tight so I let them be.
You can also swap the whole deal out...I swapped the OEM open small-case 4.10 diff for a medium case 3.73 LSD a while back. I do a lot of highway driving, I highly recommend the lower ratio.

I wish I could find a 4.10 in a medium case, but i havent been lucky yet, and the ones that are out there people know what they have and they cost a good chunk of change....the search continues
