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

Please lettuce know if it worked, so I know whether and how many eggs to throw at my face.
I'm sure you're good :) but i will do that. i greatly appreciate you reminding me about this. I literally bought one of these and have it sitting on the shelf from the last time you told me about it several years ago. lol. I offered to buy this customer one. hopefully he reports back!
