With the spring spreader still in place (it isn't removed until the very end of the job) the wishbone was connected to the spring using early Ford rear spring shackles, which measure 2 1/4 inches wide. Unfortunately, front springs, and hence front spring hangers, such as those on the '40 'bones, measure 2 inches wide. We used washers to make up the 1/4-inch difference for now, but will machine up a 1/4-inch spacer before the car hits the road. The spring and wishbone assembly (not to mention the rear of the chassis!) was supported on blocks of wood.
