Interesting date on that waterpump if it's the original..February 69.
I would imagine an #065?
Is the Radiator still holding the Prefix tag of ZE.
The Deepgroove Fan pulley should be part #3976060AP,and worth it's weight in gold.That #631AO is a NON Deepgroove 1971-74 base pulley.
Original engine..original driveline..deluxe interior..Original paint...Valve Covers w/drippers,..booster tag...5 bladed fan,etc.
I understand your day two obsession Tom,but I have to play Devils advocate here and ask,"What did this Time Capsule ever do to you?"
Go pick on a different one.
