Kudos for the write up. Really not a difficult job.

I managed to source a brass/copper core through OER.

Great information in this thread!

Eventually I plan on doing this as my heater core hoses are cut and I have no heat I do have AC though. PO got back to me and said he thinks the core was leaking and needed to be changed.

Can anyone provide a parts list of what one should have to accomplish this?

Since I have it out I plan on doing a full restore as I was taught to do it right the first time and I don't want to have to deal with this again.
