66 cuda

I seen new pins and bushings on ebay just the other day! do a search in ebay and type in 66 valiant, I would start by spraying the hinge pin's down with Blaster, It's a penetrating spay. and keep them sprayed down till the new pins arrive, I hope a tec will jump in and help you soon on the other stuff.
