I can check this weekend to see if I still have that belt in the truck. After I fixed the compressor clutch bearing, I saved that belt as an emergency backup, but I don’t know if it is still in there.
Thanks but don't spend any time on it. There's a local parts store that I'm sure will let me exchange the belt should it prove to be the wrong length, but I'm comfortable now that what's listed in the parts catalogs for non-A/C should work.
