Radiator overflow tube clip codes
 

Does anyone know the application for these radiator overflow tube clips? BA and BB

Probably 70-72 Chevelle.

BA tag appears to be correct for some LS6 cars. It’s a little pitted but complete. BB tag has part of the section that clips to the radiator broken off. Still probably OK because these typically had some solder helping hold them on. Pic attached. Sorry for the shadow.

Im curious, what different codes or even codes at all?

they look the same .....

appreciate the education!

Was this a case maybe like igntion coils-brackets where the code designated a particular hose-clip combo? Maybe the hose was pre-assembled to the clip and the hose was a specific length for the application? Just guessing here.
Although if the clip was soldered on to the tank, it kind of negates this theory. The hose would not have tolerated the heat from the soldering op.

Hose was attached later. It was more often inadvertent soldering if it happened.
