So, I found this locker on eBay...anybody wanna take a stab at what model it would fit? Currently a good price if someone was looking and it happened to fit their rig.

Sorry in advance if you are bidding on this and you are on YT hoping to keep it a secret.

It's not a locker, it's a limited slip. Probably out of a Supra. I think they had the 7.5" diffs if I remember right which means it would probably work for the front diff in an IFS.
