1969 A.C All-PA
1969 Super Cooling All-PA

From 1973 MPC

Thanks for looking up in later MPC, have that info.

Should have noted am looking for confirmation of the code from an actual '68 or '69 manual trans 4 core radiator in a B series Pontiac, or it's broadcast sheet. Realize on a '69 B series that going to be a tall order, as 3 on the tree was the only '69 manual trans choice, & most of those will have 3 core radiators.

Probably have to be from an AC car. Not likely many were built with manual trans and AC.

Definitely a tall order. I have the info on exactly one '69 manual transmission big car and someone had swapped an automatic's radiator in it by the time I got to see it (PD code, not that it matters since that's an auto). Of the '68 big cars I have 1 manual transmission car that had AC and a 4-row radiator but could not read the code (it had been rodded and repainted) and sadly the broadcast sheet was not around anymore - it was a loaded Grand Prix. I have a bunch of '67 manual cars in my list, you can definitely tell manual transmissions were on their way out just looking at the '67 to '68 numbers.

Side note as well: the TWO 1970 3 speed big cars I've seen - 1 had a leaky 3 core radiator in it and the other had a Spectra aluminum replacement. No broadcast sheets either sadly. One was a non-AC car, the one with the new aluminum was an AC car.
