I have just went through buying and rebuilding a gsr tranny. @ 1st I ordered the wrong syncros for the 3rd,4th gear shafts, so I then ordered complete gsr tranny= $950 used. Had it installed along with ACT H.D clutch, drove home (fine) got home And shattered Bell housing putted home and due to the christmas hol. Began rebuilding tranny w/ parts from old tranny.
Hell
Finally got it, Not a moderate chore. I have 2 shops that are helpful and very reputable depending on where you live?
(Louisiana)--Hope this helped after a month of putting threads on here I got no helpful response, so trying to offer suggestion
again hoped it helped.
