450 bucks for the Pope one? I'd probably have someone hack those flanges off and build me a new one for half that.

A good fab shop can use the stock as a template. They will need both the S and J. If you can source out the material needed the cost will only be labor.
Yeah, that's probably going to be my best bet for now.
