69 cud 383 4spd

Can u check your upper A arms....do they have a extra welded on piece of like angle iron about 2-3" long? This would be on the underside. Thanks, Dave
The ones on the car are not the originals. Im changing the car to big bolt pattern. Ill take a look at the ones the car came with. My cuda came with the 4 piston brakes. Ill get back to ya.
