Anyone know the dimensions of the flywheel bolts and the thread diameter / pitch.

No flywheel, just torque converter. Is that what you are asking?

He probably means the flexplate bolts.

Flywheel is what the starter engages? I could probably check latter today.

Manual Transmission = FlywheelAutomatic Transmission = Flexplate

Both are engaged by the starter.Both bolt to the crankshaft with 8 bolts.Flywheel bolts are longer than flexplate bolts

Difference being that one is for a clutch & pressure plate while the other is strictly for mounting a torque converter.

I took some off a couple weeks ago. They were 14mm and about a half inch long. Can't check the pitch right now but probably the same as other 14mm on the car.

IIRC, the actual thread part of the bolt is M12 x 1.25 or 1.5.. dont hold me to that though.

Cheers guys, I have some 300ZX ones and didn't have the engine handy to check if they were the same thread or not. M12 x 1.25 seems about right.
