Hey Mandom u can also try a late 80's and on ford small block water pump to thermostat hose they are exactly the same thing with out the adapter u have only shorter. Now that I'm thinking about it there are many Ford vehicles(Aerostar,ranger,econoline) that use that 3/4 -90 degree to 5/8 straight hose if u wanted to ditch adapter. FYI. I would go to parts hose and just look around and always find one, common hose. u seem to have this build well under control.
