i lowerd the upper a arms ,1 inch down and 1/8 inch back. it requires a little hammering on the inside as well ,just to flatten some flanging around the holes. tomarrow i am going to work on the lower control arm mount. going to make it adjustable using the brackets off an old 68 front end . no more shims to adjust the front end. the radius rods will be changed with modified 67 rods so every thing will now be adjustable. i know ,a kit is available for the lower control mount but uncle Jim aint made of money!
