66 abody frame

I don't know if you found frame rails yet; if I had known there was a demand for them, I could have saved mine from my '65 Barracuda. It was a lot quicker just to cut them out with a torch. I still have the K-member, along with steering box, torsion bars, and various front suspension components in the first photo, if you need any of that. However, it is all at the shop that is doing my car in Chicago, so a good day's drive from you.
Are you going to upgrade your frame, front suspension, and brakes for that nitrous-fed 408? That's a lot of twist for our old unibody cars. I remember not being able to close the doors after a hard run in my '66 Valiant with a fairly mild 340 forty years ago. The second photo shows my new frame and front suspension for the Barracuda--frame rails by Hot Rod Chassis and Cycle in Chicago, with Detroit Speed's Aluma-Frame suspension for a 1st-gen Mustang.
