Hey guys, I am trying to figure out what the original part number for the 1969 Z/28 fan/alternator/smog belt is. I see in the AIM it says for a sbc with a manual it is GM3883248, but then see the repop guys list a part number GM3932457, although I didn't find this in the AIM.
In addition to the part number I am also trying to figure out what is assembly line correct. I have seen 2 versions of GM belts, ones that have the GM number stamped/pressed in , and have also seen the part number raised off of the belt in a crisp font. See pic (Thank you Hans for digging those out)
Hans pic of his belts came off a 69 Los Angeles car, not sure if the Norwood parts bin would be the same, or if there was an earlier and later version of the belt(s).
