I have a leak in my radiator and am going to drain and replace it this weekend. I plan on buying an aftermarket and going with the copper/brass core, but guess the OE is plasic casing like my OEM? My local import parts store is Olmpus and they have two versions:
1. 2443 (CSF) Radiator 1 ROW PLASTIC TANK COPPER/BRASS CORE - OE #16400-50020
(90-94) for $139.00 and 2. 1304 (TYC) Radiator TYPE: PC - TOP HEADER: 1 7/8" X 30 1/2" - 2 ROW - BOTTOM HEADER: 2 3/16" X 30 1/2" - CORE SIZE: 15 3/4" X 29 13/16" X 1" - MATERIAL: PLASTIC/COPPER (93-94) for $311.00.

Can anyone tell me which one I should go with? It looks like the 1st one is OE and is a direct fit but it says it has 1 row, is that what I have now with the original factory radiator? And if so, why would I want to buy the 2nd one that says it has 2 rows, which must cool better, but may not fit directly without modifications and is more than twice as expensive? Any recommendations would be greatly appreciated. Thanks, Tyndale Cobb

 

From brief searching, the factory radiator looks to be a single row. Whether or not you have a performance difference with a 2 row is open.
