Need 64 Bucket seat foam bottoms

Legendary might have the seat foam you need. There is no such thing as inexpensive replacement upholstery for Mopars. The Year One stuff is probably sourced from Legendary anyway, then marked up. I have dealt with Legendary for two upholstery sets, one for a '67 Fury and the other for a '66 Barracuda. I'm happy with both of them. They sell quality products and they stand behind them. If you decide to deal with them, talk to Mike Saless.
