I’m looking for old magazine road tests showing underhood photos of a 1970 cuda or 1970 challenger with air conditioning to confirm which type a/c valve was used.

I know the parts books show different #s for the 70 compared to 71 valve

is it the metal valve or the red + black bakolite valve

Does anyone have or know of a magazine road test that would answer that?

I’ve heard too many conflicting stories and nobody i spoke to is 100% confident either

Thanks for the help!
