Moving rear end back

moved my pin hole back 1" on the leaf themselves for added tire clearence and open centering. shims under the perch can fix any pinion angle issue you may get from this. i also have adjustable front amd rear shackle perches to move my stuff around for track conditions. top pic moved back 28" tall 275 drag radial bottom pic you can see my front shackle the first time i did them. second hole made to allow a 1 inch drop of the front section of the leafs. i now have a multi function setup that is adjustable by 1/4" per grove like mustang team z stuff. way cooler and more adjustable.
