For the pigtails check
here. For the shifter fork
here. The flywheel bolts are 7/16 and the bellhousing to block are 3/8 I believe. Buy some arp flywheel and clutch bolts. The tranny to bell are metric i'm pretty sure, I can look at mine tommorow and let you know. What t56 do you have? LT1, LS1, GTO?
