Which radiator hoses?

Well, if you look at Be Cool radiators, they tell you the exact hoses to use. So i'd try that. Just make sure your inlet and outlet are on the same size as the Be Cool radiator you are referencing.
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.

The other option is to ben a wire the way that you need it to be and go match it up at the parts store.
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.

Another option is to buy flared aluminum radiator hose tubes from say Speedway or the like and make something up. I have found this option to work the best.
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.

I've searched the web and read a ton of posts but it seems like I'm the only person on Earth that runs a big block with a 22" radiator with a driver's side inlet.
