I am looking for the thread size of the end plate screw and the thread size of the tapped hole in the drive end of the rotor .Thanks .

Hi tdc, Not absolutely certain, but I think that the end cap screw is 3/16 BSF or cycle (same pitch). As for the drive end, the old rotor I have is too beat up to tell but appears to be 3/16. Isn't it likely to be the same both ends?

I should have included that my end cap screw is a slotted cheese head x 9/16" long and measures .1825" in diameter. Slightly under 3/16" as you would expect.
