is it possible for a garage hack with very little trans experience and ALOT of spare time to rebuild my gearbox myself?? i installed my 82zx engine and trans into my 71 240 and now want to fix my 2nd gear synchro problem. seems on 1-2 upshift there is a very brief grind with the clutch, impossible without. i have replaced slave cylinder (was leaking in the zx) and properly bled the system. grind is/was present in both cars, don't believe it's the clutch master cylinder. sorry if i'm in the wrong forum, but most racers i know do or have done their own mechanical work. if you think i could fix/rebuild my gearbox, where do i get the technical books and parts for a good performance-autocross build. thanks in advance for any positive feedback. my first post EVER!:stupid:
