I got one of my belts, power steering I think, at autozone, because I ordered the wrong belt. (Even though I don't have A/C, since I've got a 3 groove pulley, I needed to order belts "for a/c") I think it took a couple of steps of cross referencing. I think I used rock auto to cross the land rover part number and then used whatever popped up there to find the autozone version. ------ Follow up post added May 21st, 2016 10:59 AM ------ 17315 is the AZ part, but I'm not 100% sure which belt it was for.
Looks like ETC4272, power steering.
