Heater hose sizes? 71 Swinger

[Cal_gecko]

A while back, I plugged the ports for heater hoses on my 71 Swinger, thinking I was not going to want them .. I've since changed my mind and don't remember what sizes the hoses were .. I am going to swing by Pep Boys in the morning to get new hoses to install at the same time I replace my radiator tomorrow... I'm thinking 5 feet of each hose is plenty.. but I don't remember what the ID of the hoses were - I recall them being 2 different sizes.. anyone know?

One is 5/8", I believe the other is 3/8".

IIRC, one is 1/2 and the other is 5/8...but...most 5/8 hose you can find easily is slightly larger O/D than what came from the factory, and it's somewhat difficult to work with.

Finding OEM spec Mopar 5/8 hose has been an issue for decades.

If anyone has a good solution, I'd love to hear it.

3/8th is way too small
i think 5/8 & 1/2 might be good, but i think you can use 5/8th on both it will crush down alittle on the smaller line. i'll stop back in because i have to do the same thing on my car but also i have to do the core first.
It's missing from my car. Go figure the guy in california didnt need heat strange???

One is 5/8", I believe the other is 3/8".
