Just as the title says, I'm looking for the part number of a Goodyear Gatorback serpentine belt for a ZZ4 350 (1990ish build year). My google skills have not been productive =( Thanks!

I've used Gatorbacks in the past with good results, but I'm open to other belts as well if someone has had a better experience.

GM Part #10085752 for stock belt that from what I can tell is 94 - 94.5" or Goodyear #4060945 for 94.5" or #4060940 for 94" in a 6 rib Gatorback serpentine belt

I think it really depends on the brackets/accessories you used. 3rd gen, truck, 4.3l van, GMPP, if there is an air pump delete pulley, etc. I went through 3 until i hit the one that fit my setup best. Now I had this exact setup and ended up with a different belt. I'll see if I can find the part#.

GMPP one:

Well, I should have mentioned I do not have an A/C unit so the stock GM 10085752 won't work. I'm honestly not sure if it is a stock ZZ4 setup since the previous owner used a March pulley setup. I'll have to dig through the receipts, I think it has the original March part number to help narrow down a belt.

It also has an electric fan, not sure if the ZZ4 came with a mechanical fan on the pulley.
