I have picked up several radiators for 68 to 77 for A-body cars Chevelles Skylarks Cutlass Gto Nova's ...I guess you might say im starting a bone Yard of OF Harrison radiator tank stock as I get ready for the Harrison Restorations and having the speical cores made to Restore these rads to original condition .. this link may give some insite to what im trying to accomplish http://www.chevellecooling.com/67.html?sm=53057

I have seen the tags on parts place web site and they dont cover all the bases such as earlyer Skylarks 68 or 69 they list 44 different tags for models but dont cover all the years ..but what I am in direr need of is the information on the suffixes in the tags to know what cars they will be appropriate for .

Im getting a general idea of what the large letters stamped into the outlet tank mean .. but the numbers in the tags and the smaller suffixes are a mystery at this time .
If anybody knows where I can get this info , as a chart or manual of CD it would be greatly appreciated ...At Team Camaro I came across the CRG site great info there .
I hoping theres another like this form for Chevelles and so on .

I have seen some info here in restoration concerning the large letter code stamped into the tank such as

I would hope theres some more info out there as to the other sufix's on the tag.
been searching for weeks .
Some information was printed in old Chevelle Report magazines which was a monthly publication put out by the NCOA (national chevelle owners association). but I havent had any luck finding the info on the net .

please feel free to post here or private message me if you have info on where to find the documentation info

thanks again Don
