Hi Spencer, found out the crank dimensions:-

For 3.2 d1 (std main bearings) = 60.020 - 60,059
d2 (std rod bearings ) = 55.020 - 55.059

For 964 d1 (std main bearings) = 59.971 - 59.990
d2 (std rod bearings ) = 54.971 - 54.990

My rough vernier measurements really aren't even close to being accurate enough, I just took them to get a rough idea. I'm going to measure it properly tomorrow at work if I get time.

Thanks vmisquez, they're going to be replaced as I have no idea how old they are, just not sure which ones to replace with!

On a seperate subject - Has anyone changed their valves to the lighter 993 ones with the 8mm dia shaft when rebuilding a 964 head. If the guides are shot and need replacing it seems a sensible enough 'upgrade' to do???
