I like Gates. Measure the lengths you need with a string, take that/those measurement/s and the water pump pulley with you to the parts store and get the ones that fit the pulley and that length/s.

my problem is which store I work for a shop but we mostly have the serpentine. napas belts as of this year do not sit in the aluminum pulleys correctly even when dead tight with no movement and I tried all different tension points. the napa belts seem to be to wide I need them about a eight thinner. do you have a proven store that sells the right widths? I might have to rely on swap meets for nos belts otherwise.

Belts are not supposed to be bottomed out in the shiv.

NAPA belts are made by one of the major manufacturers, so they should be the same as belts you find with a name brand on the package.

If the belts really are too narrow, look at a manufacturer's site such as Gates for the dimension specs for the belts and look for one that is wider.

Try either Gates, which make Napa belts, there is a difference of design between the the two. Another to try is the Dayco Top Cog belts. I find they both stretch a ton, I need to go a size or two smaller than recommended due to stretch.
