Heater hose

[Texas charger 73]

im currently not home and have a question.. im looking to hook the heater hoses up on my 73 charger small block... i have a 5/8" hose, but i keep reading conflicting sizes on the other hose.. i have seen 1/2" and 3/4" mentioned.. does anyone happen to know which one and proper connection of hoses from nipples to water valve to heater core

 

[R413]

If you car is factory heater core and engine it has a 1/2 and a 5/8” heater hose, AC and non AC. If it’s been swapped then no telling what is there.

Mopar didn't use 3/4” heater hose, at least mid 70’s back to late 50’s.

Measure all four nipples, R413 is correct if stock.
