Sorry now I understand, I browsed around and do not see anyone offering one for your application, so one of three choices, buy the adjustable and have a shop bend the end nearest to the rear axle mount,( these are tubular steel, not solid ) have one made from scratch or change the frame mount to the 1964 style so its straight across to the axle mount. I know this is something you didnot want to hear...third choice might be cheaper if you had a donor truck...
