Al, I think you will find the rebuilts use the same only- available
flyback, which is probably the aftermarkets in the kit. I might be wrong.
I've heard other times, the whole module was the only cure for
intermittant failures. To their credit, I've fixed many with the kits.
Just depends on the failure I guess.
