Wow, those have gotten expensive. I built my Duster just a couple of years ago and I was able to buy a NOS one for $150. Local guy had it stored in his shop with a bunch of other Duster parts. He decided he was too old to build the car so he was selling off the project. It was brand new in the Mopar box. The original that I had wasn't in bad shape, had one split in it. Not sure what I did with the core. Maybe tossed it. Didn't realize they had such a high core charge on them.
