Just got the original 2998874 radiator back from Finger's Radiator in North Brunswick NJ. They did a great job and even got the dent out of the top tank. It was recored as a three-core instead of the original two-core style. Took about a week and cost $450. They also did the radiator on my Grampa's Lincoln a couple years ago for the same price. It's a good, old fashioned shop that has been in business for 92 years.
