Hi Greg, Any of those mentioned above would be fine. There are also a few guys out there that do AF repairs. Here is one... https://www.youtube.com/watch?v=IAZM2tTmeo8
I think Neil (in the video) may do work for others as well, he has a bunch of similar videos out there.
I interact with some on a Facebook AF page, you may be there too, not sure.
There was another guy I was gong to suggest but it looks like he is closed for business.
