Yep, Adams list is pretty much it, check it all out before you pull the motor. Also try packing the pump with grease to rule out cavitation. Also try a new pump. You are priming it with a reverse rotation drill aren't you?
Glad you like its look because it ain't changing bar some blending and 'weathering' over the fresh repairs. Plenty still going on. Back end all new pretty much....
Like all bloody old cars, the Charger was a bit more rotten than i thought. Saying that, it was described by the seller on Ebay accurately. The roof was pitted, which became holes when poked hard.
Not sure whether to 'weather' a vinyl roof or just keep it new. OR i could dust the roof over with matt black and let the surface rust have a good stain. Tim reckons a vinyl top (as per factory).
