G'day mate,

You'll be able to get the lock tabs from Chevs of the Forties or Jim Carters. They also stock the torque tube bell seal and gasket kits. It will also pay to unscrew the collar on the end of the bell if you haven't already done this as it allows the bell to slide back further. The rear yoke will slide back on the driveshaft and allows enough room to split the coupling. If its a 4speed trans there should be a bracket which bolts onto the crossmember. When you put it back together make sure you clean the threads well and use new lock tabs. You can also use red loctite on the threads of the four wee uni-joint bolts. Yell out if you need any more info.

All the best

Bob
