someone told me that cars with a/c had tinted glass and non a/c cars had clear. is that true? thanks

No.
Normally A/C recommended tinted glass (G11), but clear glass could be ordered (G21).

There was a third option of tinted windshield only (G15). As mentioned above tinted glass was not required with a/c, however most a/c cars were was usually ordered with all tinted glass (G11).

On non a/c cars the tinted windshield was a common option, and some had all tinted glass, but was not common.

Alan,

Purchased a challenger RT from Canada no a/c. Broadcast coded for all tinted glass.

Great. Sounds like back in the day you could just about order anything you wanted.

Thanks for all your imput. i appreciate it.

Dan and Bob,

Thanks for the info. Looks like full tinted glass was much more common on non-a/c cars than I thought!

Guess I shouldn't use my personal experience with old mopars to generalize for all old mopars.
