76 cab swap headaches
i went to throw the clutch pedals in the truck today ( for t hose who havent been following my saga over the past year we have a 76 C 10 that was a rot bucket. We put an 81 cab on the chassis. The original cab had a 3 sped on the column this one had the clutch pedal removed and i couldnt get the old clutch pedal in there so i bought a pedal assembly out of a 78 blazer from one of the members here today we went to stick this in.
it turns out there should be some hole through the floor board where the clutch push rod goes and it wasnt in this cab. The cab was originally on a 3/4 or one ton truck so i figured out where the hole should ahve been and made a hole to accomodate it, hook up the linkage and get it all together and the clutch wont dis engage so when you start the truck it stays in gear It also appears that the clutch linkage attached to the transmission smacks into the floor board and doesnt have enough room to fully swing The arms on the transmission seem to have gotten stuck now and i cant seem to get the tranny ou t of gear and if you try to start the truck it moves with the starter gear ( like if its in gear and you aint pushing in the clutch while starting). the truck wont come out of gear so next warm day i need to see if i can get the linkages loose so i can see if the transmission is good yet. now my questions is this does anyone have a 76 c 10 with a stick shift preferably a 3 speed stick who could post pics of the clutch linkages under the dash where they go and the entire clutch linkage under the truck. Better yet any of you who have firsthand knowledge of this kind of stuff in the NJ area have time to come and look at this cause its ben a while and i dont remember if i put it together right or if im missing something or anything. Ive looked at the haynes manual and the factory service manual and it looked ok but maybe i meesed up thats the joy of not touching the truck over the winter you forget stuff lol TIA for your help

hmm I have seen this problem before where the clutch wont disengage.. I cant remember what the exact cause is. Are you SURE that the clutch is capable of being disengaged? I think it had something to do with the clutch assembly being installed backwards.
![]() Was the tranny shifting fine before it got stuck in gear? The last time I had to fix that problem, someone installed the shifter w/o aligning the forks or whatever is down in that hole on the top of the tranny.. it was like it was stuck in one gear and there was no way that shifter was gonna move. I would remove it and double check. it cant hurt? Wish I could be more of a help mike |

the truck ran and drove when we parked it. we did the cab swap prolly late november or so, and at that time we disconnected the linkages from the column and the clutch linkage from the cab. we then swapped out cabs. We had the tranny linkages hooked up and it worked ok. we couldnt install the clutch linkages cause the clutch pedal wasnt hooked up in the new cab ( it had ben a standard transmission but had ben converted to automatic and the clutch pedal removed) we since located a clutch pedal assembly from a member here and it sat in the garage for at least a month or two before today as it was the first decent day out so we dropped out the column and changed out the entire bracket and pedal assembly for the brakes and clutch, and thats when the troubles arose when we thought we had it together and tried to start the truck. we got the truck into some foreward gear and the clutch didnt seem to disengage cause it would just turn the motor and drivetrain . we tried manually pulling out the arms but it locked up about that time we got annoyed with it so i stopped messing with it and dropped the driveshaft so i could move it i figure next warm day ill mess with it but i wanted to see what the guys here had to say first
