The expensive Glen Ray radiator I believe is if you are buying a "correct" numbers matching / date coded / penstar embossed radiator. They have other less expensive options. I think they can stamp correct numbers in new tanks without the Mopar penstar logo and save you about $100 in Mopar licensing fees?
If you can get the correct tanks, they can put them on a new core. Anyhow, call them up as they have several options and prices.
