What year and make car, A,B,E or C body ? I have a aftermarket tubular stock replacement K member for a early(pre 1967) A body that weighs one pound lighter than the stock K member . I'm going to send it back to have it modified to a front rack and remove the stock steering box mounts and stock engine mounts,( I'm using a front motor plate for a BB) remove the torsion bars and so on. I'm hoping those changes will lighten it up some
