Goodyear Poly-V Belt Part# for slightly smaller pulley???

[V6UnderPressure]

I am looking for the part number if anyone has it for a slightly smaller belt than stock (200amp alternator has slightly smaller pulley than stock) Does any one know the correct part number/size? Summit doesnt have a comparison chart for Dayco/Goodyear.

I just went thru this very thing. The p/n for stock TR, in Dayco, is 5060640. The 640 part referrences 64.0 inches in overall length. I put a 5060630 on with the RJC lower pulley and Kirban's overdrive waterpump pulley. Works perfect and as a side note, the shorter belt is almost exactly half the cost of the longer?!

Use the same number but start with a 4, 5060640 will be a 4060640 goodyear, Just tell the parts dude that you want the = to the dayco number, goodyear might be close. Like a 4060641 or 4060642 and so on.
