I need a T-3 spacer/ wastegate adapter
 

I'm looking to put an external wastegate in between a stock T3 manifold and a T3 turbocharger.

I'd like to buy a non-divided T-3 spacer that has a pre-existing wastegate flange popping out of the fat side, but I don't think such a part exists.

Otherwise I'd buy a non-divided T-3 spacer that's at least 1.5" long and weld my own little flange onto it, but I don't even know if that part exists either.

PM me if you can help me out, please.
