Radiator identification

Yes, I brought it to a decent radiator shop in NJ. He cleaned it but there's still build up in the cores, he will need to detach the tanks to clear the cores properly, he said they are clogged internally. It is a 22" and the triple cores look like they may be 1/2" as HemiDart mentioned. Hes gonna take the time to do it properly and will paint it Satin Black, looks better than the Gloss Black. Ill get this one back in tomo and probably call GlenRay and order #2949065 as Mattax also mentioned.
Thanks guys, the information was prompt and on the money as usual.
