I've been reading posts about new radiators and was looking into the Autozone 3 core copper radiator. When I look up the part on Autozone.com I can only get a 1 row, but when I look one up for a Firebird, I can get a 3 row. Will the 3 row Firebird radiator fit my '86 IROC and have all the correct fittings? Or am I just misunderstanding what they mean by row? I read another post that said they got one from AZone for $118 and that is what I am coming up with. Thanks

 

the 3 core is a copper radiator. the 1 core is an aluminum radiator. both are interchangable between Camaros and Pontiacs as long as the engine stays the same. (ie a v6 will not fit a v8 car.)

 

Thanks, that's what I needed to know.
