I recently bought a beater 3/4T 73' GMC, with a 350sb, and factory a/c. The radiator has been replaced, at some point, ..with one that is not tall enough. It has no contact with the original upper "flat" top plate, which is designed to keep it secure. Not good.
I've seen these "shorter" radiators, with "step down " top plates, on some trucks at the salvage yard. I found a 17" and a 19" tall radiator, both listed for this vehicle. I'm assuming that a replacement should be the same height as the original, for proper cooling.
What factors, ...determine which radiator is used. Saw a "shorty" in a factory a/c truck, at pick- a -part.
Appreciate the help/info
