I'll keep my eyes open for axles and send you links when I find them. Please remind me if you don't hear anything from me in a few weeks. They seem to pop up and I bet I can point you to one, but don't want to be a middle man in the deal.

Detroit's are reasonably common everywhere, last several good deals on 4-53T's I've seen were in CA. And I'm in CA at the moment and was playing with a 4-53 earlier in the week.. Saw two Detroit conversions at a show today also in CA.
Just look around and most anything you want will show up given some time.

Not suggesting you need one, but decide what you do want and look for it, you'll find whatever it is soon enough.
