In the middle of a T56 swap from a 97 Camaro and I'm trying adapt the clutch master cylinder. The Ebay clutch pedal had a worn pushrod pin, so I need to replace it, but I noticed that the pin OD is much smaller than the master cylinder pushrod bushing. Should I drill out the hole and put in a thicker bolt/pin?
BTW, if anyone has pictures of mounting brackets for the master cylinder, I would be most appreciative. I know I can adapt a truck master, but adapting the hydraulics plus price of new master is prohibitive. I just have the mentality that I can't pay for something I can make!
