I'm ordering a 833 rebuild kit for my 1970 340 Duster. The supplier keeps asking for a tooth count on the gear set. Don't I have the 23 spline? It's a 323 posi. What's he talking about?
He may be trying to figure out if you have early or late synchronizer assemblies. '70 340 would be the cut off. If your car was an early build it would have the early synchros...if it was later it would have the later synchros.
