2949015 Radiator with 78 360 motor.....needing hose numbers.

I agree on the trial and error process....
I've got an email into Gates to try and identify the hose currently being used. Hopefully they can cross it. None of the local auto shops (nor I through google) have been able to cross the 6K21 EBP 80M-150. I'm sure I can find something close that I might need to "cut to fit".
