I have a 71 Cutlass Supr. w/ 350 engine (no air cond). What radiators are interchangable with my Cutlass? Could I use one from a '72 or other years?

 

Am not sure what radiators will interchange from other GM models but I would guess 70 to 72 Cutlass would be the same maybe even 68 to 72. You can buy a new radiator for your car or have yours repaired or re-cored. I wouldnt bother trying to find a used radiator of he same vintage as you already have because chances are it will have the same pending problems.
