68 Dart Power Steering hose small block cant find a replacement

I even went to a franchise hose maker who would not make it because it travels on a public road

Tell them it's for a homemade log splitter on your tractor.
They'll write down "tractor",
Yep, just take it back to them and tell them it's for a 1972 Allis-Chalmers.
