The last re-core I had done local to me cost me 450.00 for a 22" radiator. With that said they did not straighten the tanks or do any type restoration work. Just recore it and put It together.
I had Bob and the gang at Glen Ray do an 048 radiator for me and yes it's expensive but it looks absolutely beautiful when you get it back. I had that one built with his max cool core.
If I was doing any factory radiator I would give Bob a call as I was really pleased with their work.
