Background. When reassembling my front dash on a 88 JDM BJ74 i realized i had a leak in the front heater core and one of the copper connections had broken free. I put it all back together minus the heater core and bypassed it with some heater hose.

I have a new heater core in route and I am looking to reconnect it to the system using gates flexible heater hose as opposed to the original copper connections as they are not fitting properly. Can anyone tell me the correct diameter for these by chance.

The truck is in a storage unit right now and I would like to get the parts ordered as quick as possible. Thank you.
