Ha ha ha. The "pilot" word is also a highly technical term for that part
of the starter that locates the starter in the large starter hole in
the redrive plate. In both of my cases it is 2.63 inches in diameter.
I need you to measure that diameter too if you can pick yourself off the
floor laughing.

Sorry. I never could resist a straight line.
I don't have accurate calipers, but the 2.63 seems about right. The bolt
holes are about 1.7 and 1.15 from the edge of the pilot ring. Apart from the
"gear shade" it looks identical to the left hand one in you're picture.

Well the bolt pattern appears to be similar as well.
