My 9" ford rear end has a 4 link set up.

The lower arms are straight pieces that come straight back off of the main frame rail.

The upper arms are straight pieces that are at about a 45 deg angle from the main frame rails, pointing outward as they go back to the rear end housing.

Both upper and lower arms are aluminum pieces with absolutely no adjustment ability. Simply have a hole at each end with rubber bushings and a bolt passing through.

Is this the standard set up on a A&C Cobra? I think it was purchased as a roller around 2001.

Any ideas on the best way to adjust the pinion angle?
