1962 Valiant rear frame rails needed

Hey all.

I need to replace my rear frame rails on my 1962 Valiant A-Body. Since I will be into it, I want to replace the entire length both sides. Has anyone had any success buying pre-made rails from any of the shops out there? Can someone point me to a good supplier?

I saw some at Classic Industries, but the cross-section did not look correct in the picture on the web page.

thanks!
