71 Cutlass Radiator replacement help

Hi All - the radiator in my 71 ragtop needs replacing and I would like to get some recommendations as to which one will be a drop-in replacement. It's a stock 350 cid engine.
Many listing on ebay and other sites are a bit confusing and I am concerned about getting the wrong one, especially with the wrong size for the hose diameters. I've not taken the old one out yet but I know it is the original from when I first got the car in 1974.
Any hep and suggestions are appreciated !
Thanks in advance
Joe Hackettstown, NJ

Most of the aftermarket stuff is for the '71-newer engines with the smaller diameter lower hose, so you should be OK there. It's finding the parts for the '70-older that have the larger diameter lower hose is the problem.
