Interesting. I believe the "HT" means heated rear glass (which gives you the 80A alt & idler pulley) The way I am reading it is the 485397 would be correct for the Black car. (455HO with a/c and HT)
In other words, ALL 72 455HO Air Conditioned cars use the 485397. Including automatics and manuals. And if you have a non-455HO car (350, 400 engines) but you ordererd HT (heated rear glass)-you would get the smaller 485397.
The 481040 pulley would be for all other cars (350 & 400's) with A/C.
I'm looking at 72's specifically. Am I interpreting this correctly?
