Contoured Frame Rails
They are from us car tool and are still in the original unopened box as delivered to me....I don't want to open them.....I have had them for 3 years.
They came in to late for my 67 build and since I replaced or am currently in the middle of replacing my wifes 69 floor pans I know they wont fit right......pans that I have are cheap repros.
Go to US car tool for the specs...169 is what i paid.
