After you rebuild the pump, bolt it on without the gasket to make sure the shaft is not rubbing on the thrust casting in the head. I had one that I thought was good to go but the shaft was rubbing. Had to grind the end of the shaft a little to fit.
The radiator is an aftermarket replacement. They as far as I know are still making radiators.
