Hi Sy

Ill be doing the rebuild myself. First Ill be putting in a shift Kit to try to clear up the sliding problem. We had the exact same problem occour on my father in laws 87GN when he hit 12s too. He also thought it was time for a rebuild but one of our buddies said to go with a shift kit and see if it clears it up. Worked for him but my car has 100000 miles more than his did! Ill let ya know if the kit works Ill be back looking for 12.2-12.3s.... And Autocrossing next month! See ya
-Bob
