My 1966 Valiant Coupe

Hello
My name is Lon. Just bought a 66 Valiant hrdtp that needs a lot. It has a very tired 67 318. It also needs all new weather stripping, swipes, door end rubber, weather stripping on the chrome mounding one the front of the rear windows and the door laces. I may have a line on a 340. Can anyone point me to the right company or person for the rubber parts? Thanks for whatever you can do.
