Radiator Hose Part #3780656 Superseded from #2863230 ?

I have a NOS radiator hose part #3780656 (1973?) that I think is a superseded number from the original #2863230 (1969/70).Does anyone have a way of verifying this? Thanks for any help

try punching the part numbers it to PartsVoice n see if any of the NOS suppliers have either # listed.
