"I ordered a new heater valve for my 'time capsule' Twin Cam and noticed that the water inlet pipe on the original is about ½" shorter than the replacement. The fittings are yellow plated, rather than the silver of the originals. The screw that holds the clamp for the water control cable is held by a weld nut in the original but the replacement has only a thread cut into the plate (probably satisfactory as long as you don't disturb it too often).

The other interesting observation is that the date on the original body is 2/1960 which means the valve must have been replace under warranty (build date for the car is 3/59). I've had the original cover re-plated and have swapped it onto the new body. -- Mark
