i have had to put this into my 92 4Runner because of a engine swap.
i have a couple or Q's though.,

The one on the car now is a top shift one but leaks badly, i picked one up from ebay that seems to be a front shift one.
I was hoping to replace seals on ebay one and swap over.

!st, is it possible to change the front shift to top shift?
2nd, if i wanted to just replace gaskets and seals so i know its good when i put on which ones would you recommend i did and any part numbers would be helpful

thanks in advance.
