Flywheel nut thread

Flywheel nut thread
So I am still trying to get a working motor in my FB. I picked up a 12a from an ex-racer who told me that his nephew rebuilt the motor from the best parts of 6 motors that they disassembled. He said that the chrome on the housings is good, the irons are good, the rotors and e-shaft are good. I went to install my freshly resurfaced flywheel, and realized that the threads are a bit boogered on the e-shaft where you thread on the flywheel nut. I was wondering if anyone knew off the top of their head what the thread was, so I could source a die and clean up the threads before attempting to install the flywheel.
Thanks

I use a small triangle file to clean boogered e-shaft threads if I ever encounter any.
I just checked. Pitch is 1.5mm. Same as exhaust studs. It looks a lot finer than that, but only because it's so big! Anyway that is why the threads are easy to clean up with a small triangle file. So save yourself the trouble.
