1965 Factory Air Pulleys and Belts

Thanks for the confirmation. '65 FPC calls out 1x "Belt, Engine to Compressor" (2268 222) and 1x "Belt, Engine to Alternator to Compressor" (1945 343) for A-bodies with 273 and factory A/C, but also calls out both single-groove and double-groove compressor clutches for 8-cylinder A-bodies with A/C. No distinction is drawn in group 7-03 (cooling system/belts) or group 24-25-20 (compressor clutch pulleys) between factory and dealer A/C. So…I can't help clear up the mystery. Sorry!
