I just swapped in a sm465/205 into my 83 gmc pickup. I used a hydro setup with brand new clutch/pressure plate, brand new clutch fork, new throwout bearing, new slave cylinder, and reused the master cylinder. I have the clutch fully bled, and it seems to be working fine, but when i have it running and try to put it in gear, it won't go. It is like the clutch isn't engaging. I've got the tranny hump out, and i sit there and watch as i'm pushing the clutch pedal and everything seems to function properly. I don't know what to do. I thought it was the clutch fork, and then the slave cylinder. Now i'm thinking the ball pivot stud. I don't know. I need help.
