$517 for a converter refresh?

Their XTM model. Nothing crazy, maybe $650 instead of 500.

Kind of odd, they suggested the XTM initially but later said it's too tight for my application, that I should have a 2300 stall vs the 2000 that was in there.

Probably could have sold me a bolt together billet if they had tried.
So you're wanting a stock converter then.
