I would hazard a guess that the later A body radiators fit the same. More info on what you have: current rad cores/thickness/schroud/rigid fan with many blades/MP thermal clutch fan/blades halfway into schroud/small WP pulley/pump impeller # of blades/anticav plate. it pretty much comes down to (1) air flow (2) water flow (3) rad capacity or likely a combo of all (3) & timing and AF ratio needs to be at least in the ballpark. Yes it might be as simple as needing more radiator. EDIT I missed the most important part, WHEN is it running hot? idleing, stoplight to stoplight, cruising speed, accellerating. MORE EDIT & you want a 180 or better stat, which that ain't the overheating cause but it is not a solution to go to a 160 (just sayin).
