Weird 904 to 408 magnum starter interference issue. Dakota starter won't fit? 64 push button trans. is that the problem?

Maybe the shop should be called outside one FABO members should avoid using?
Sorry, by common, I mean the 904 starter deal Is more common that I realized. Not that the shop ripping people off is a common thing. I don't have enough details to do that. For all I know it's a car dealership with no classic experience, and no idea how much info they were given by cust. Or the reseller for that matter
