Installing (owner assisted) the Plane Power alternator STC on my 1959 172 with the con o300.
Removed the generator and gear assembly.

While attempting to remove the "drive" key (read woodruff key) damaged it.
I can't find the appropriate size woodruff key for the reinstall of the gear assembly on the new alternator shaft.
Plane power has yet to respond to this issue.
the install guide pg 4 mentions 11-1006 for the "drive" key but that isn't a part number and nothing results in a search for 11-1006.
The complete replacement gear assembly (sold separately) is mentioned in the install instructions but then when looked up on aircraft spruce does not include a "drive" key.

Anyone have any idea what appropriate size woodruff "drive" key works with the plane power alternator STC er14-50?

Thanks!

Try Home Depot or any local “real” hardware store.

Turns out the drive key is included in the stc just wasn't in the box... Part is in the mail.
