Rotax 532 Type A Reduction Drive Question

Hi! I am trying to help my friend find crankshaft gear and the adapter
plate for the Rotax 532 reduction drive. He just bought the following
of e-bay:

and needs the missing parts. I've found a schematic for the drive he

http://www.ultralightnews.ca/adrive/ and if I understand it correctly
he needs #2 and #12 from there, with #12 having one of the three listed

ratios depending on the box that he got - is that correct? What's a
good place to look for parts? He's an ex-pilot and a great mechanic,
but he is not very comfortable with the internet... Also, is there a
place to find electronic documentation for the 532?

Thanks for your help!
