Looking for an 064 flywheel

I have an 064av that was given to me. Here's the problem:

The coil is bad, but they no longer make that coil (1122 400 1303). They do make new coils (1122 400 1300), but then the flywheel has to be "upgraded" for the coil to work. I need need the newer style flywheel, either part# 1122 400 1201 -or- 1122 400 1203 with a double keyway.

I don't want to pay the $141 from the Stihl dealer. If anyone has one for sale for reasonable, I would love to buy it from you.
