I bought a automotive belt for a non-standard application. It fit well and looks like quality material. I suspect that it will hold up over time. I'll let you know if not.

I needed a slightly shorter V-belt for a Chevy 350 application with a Vintage Air compressor set up on an accessory drive. I needed a belt about 10mm shorter than original to reposition the compressor to clear the belt from aftermarket control arms installed with a suspension project. Worked great!
