Does anyone have a chart on the radiator codes for 66-67 GTO ? I have several original radiators with the small metal tag with codes like "TX" and "TS".

Thanks

The codes are deciphered in the GM parts manuals and in the GTO restoration guide

I did see that in the GTO restoration guide, just didn't know if that was complete, thanks.

TS =3-4speed GTO with tri-carb or heavy duty cooling/trailering/Special axle ratio
also 67 4bbl manual HO, and Heavy duty rad. trailer, and special axle ratio

TX = 1966 automatic 389 4 bbl and tri-carb WITH airconditioner except s.wagon

can you post a photo of the tag on the radiator?
I like to see what an original radiator looks like with the tag since i am doing a concourse restoration now on my own 67
Thanks

Sure, here you go.

Is the BA tag on the same radiator as the TS tag?
I think the TS tag is located up by the upper rad hose? right or wrong?
where is the BA tag located?

[z06gto]

Correct, both tags came off the same radiaitor. The TS tag was located about 3" towards the center from the top hose and the BA tag was almost dead center. Both tags faced towards the engine. My TX radiaitor doesn't have any type of small tag. This is the only radiaitor I have seen with the small tag, ever.
