what do all these numbers mean on my radiator tag?

UH is application and thr IM and OD are the end tank codes...to much paint to see the part number . Check out CRG section on cooling > http://camaros.org/coolingsystems.shtml

It looks to me like the 68 Z28 radiator or 6cyl with A/C. But it also looks like the repro tag I bought at Rick's. It is supposed to be IH instead of IM and the tag I got for Z28 had this same IM instead of the correct (according to the CRG report) IH on it and so I returned it. Supposedly, they got incorrect picture and tag for 68 Z and that has been corrected. I don't know what IM is as its not listed on the CRG report. Kurt or John Z might know what that is. Also, if this radiator isn't right for your car, PM me as I'd like to discuss further.

Looks like a repo tag.

It is a repro tag and I've never seen an IM tank. The tag is incorrect (but how many people would notice.....).

I probably wouldn't know if it weren't for CRG's excellent article on that exact thing and the fact that I bought one of these from Rick's and it looked exactly like that one. There wasn't a picture of it, but when I got it I said "what the heck is IM?"

ok thanks guys.... i had no clue what all those numbers meant....
