The following is edited info From Bruce Tweddle that was posted on the CLF. Bruce lives in Canada and is the VW "ZF LSD King".
"The OEM supplier to Ford is Gates. I have not found a source for
Gates belts with the name Gates on it without the strength robbing
cogs. So I get mine at the Ford dealer labeled Motorcraft. For an alternator belt get JB-361L. For a generator belt, JA-357."
Useful if you're stranded with a broken belt near a Ford dealer. Personally, I like the cogged Gates belts.
