I was just at Garlits car show this weekend and had long conversation with a guy who had his 72 Challenger with Hellcat motor there.
He used the Bouchillion 90 deg adapter with TTI mounts and headers, stock K-frame and power steering pumo .
It all fit with no issues.
Makes me wish I hadn't just dropped $900 for the Borgeson gear.
