I need some info on the gear that is on the tail shaft in my old buggy. I have a 74 camaro with a 73 motor(350) and tranny(350. Not sure about the rear end but I would guess it to be a stock 3.23. Speedo quit and I pulled the tail shaft housing. the gear that is on the tail shaft moves around pretty easily. I put it back in place and hooked everything back together and it worked for about a mile or 2 and then no more. Does that gear have a clip that it needs to hook onto the tail shaft or is it supposed to be able to slide around some. I would guess a part is broken on it but I cant find any diagram or info on this to try to figure it out on my own.
