hi i currently have the source to two 4.88 toyota thirds for really cheap, and want to throw them into my 85 4runner project. question is, will i be able to install a locker into this third? i called the local 4x4 shop and they almost had a heart attack saying they couldn't have a locker installed.

I see no reason why you couldn't purchase a locker for them.

If they are factory 4.88 3rds from a 2nd gen 4Runner then they are indeed different than any other 4.88 R&P that would go into a non factory 3rd. That being said they still accept V6 lockers just like any other V6 8" 3rd. See here for more info: http://home.4x4wire.com/erik/diffs/
