Can't find upper radiator hose for 67-68 383 or 340 with 22" radiator

Thanks for all the input. On ForBbodiesOnly, someone said "Gates 21794" for my 383 with the 22" radiator. Said I may only find it on Amazon. For the 340 and 318 looks like the "Gates 20594" is the correct hose. Guess I'll be ordering both so I'll have them on hand.
