I have the QA1 tubular K-frame and the Flaming River steering coupler. I'm hoping not to have some of the clearance issues I've heard about. TTI makes a great exhaust system I refuse to hammer them to make them fit.
I'm using the QA1 K frame and the Borgeson PS box, with their steering knuckle. So, sounds like we have some similar equipment. I'm looking forward to your findings.
