Will these fit (AC Delco part #'s 9433773 & 9433753)
Was looking at buying these NOS belts for my '72 U code Supreme with A/C and heavy duty cooling.
The ASM shows part #'s 411234, 411235 and 411236, but dunno if 9433773 and 9433753 are the same, and no luck on the inner web.

I get the following P/Ns from the parts book (Jan 1972 edition):
A/C belt 411237 3/8" x 61"
Alt belt 411236 3/8" x 58.5"
PS belt 1374979 3/8" x 45"
Those AC numbers you provided are not NOS factory belts, they are generic AC replacement belts. 9433773 replaces 1374980, which is 1/2" x 60.5", so not really correct for your A/C belt. 9433753 is 7/16" x 50.5", so again not correct for any of the three.
I'm showing the current AC Delco replacement part numbers as follows (note that the last three digits of the P/N are the length in inches):
A/C belt 15612 (61")
Alt belt 15585 (58.5")
PS belt 15450 (45")
A/C belt 411237 3/8" x 61"
Alt belt 411236 3/8" x 58.5"
PS belt 1374979 3/8" x 45"
