I don't see that on the BeCool website, and I don't see any downflow 22" radiators either so even if they did list a radiator hose, it wouldn't work.
Like I said, the parts stores here don't stock parts for old cars so I'm skeptical of finding anything that way. It would be easier to just take the old hoses in to try to match up anyway.
I'll look into that but I'd really rather have a simple rubber hose solution, and the price on those looks pretty steep to me.
