they were two separate OPTIONS: H51 = Air Conditioning & G11 = full tinted glass

tinted glass was "recommended" with A/C, but not "mandatory"

but (1970) Chrysler would build an A/C car w/o tinted glass as long as G21 = clear glass with A/C was specified, if it wasn't specified the car would get built with tinted glass & the window sticker would show the additional cost.
