When buying a replacement radiator the row count and the fin count per inch is very important. Stay away from the 12 fins per inch radiators no matter if it 3, 4 or 5 row. What you want is asmany fins per inch of tube as possible. !6 wuld be great. Then count down from there knowing the closer to 12 you get the less cooling you will get. The dimple core radiators are not something I care to run. They are impossible to rod out very well. Stuff gets trapped in the dimples. This design was to slow down the coolant as it dropped thru the core... Not one of the beter ideas now was it...
