Well, my van matches one of the diagrams on that page, G00094757. There is no non-A/C diagram, but it looks like a shorter belt would work fine. I ended up going with a 3.5" shorter belt, a Dayco 5060825. Belt part numbers have the length in the last three digits in tenths of an inch. Or at least this series of Dayco belts works that way. So I used a 5060790.
The belt rubs the A/C pulley, so I removed just the pulley. This keeps the compressor connected to the lines and prevents contamination, in case I want to pony up to get my A/C back.
It looks like it was designed to have A/C as an option, but I bet they didn't sell any without. The belt is readily available, but is not listed for this application.
So it looks like I'm all set. It was raining today and no belt squeal, so it should be tight enough. And no burning belt smell.
