The POR will do an excellent job of keeping the underside and top of the floor preserved. The inside of the roof looked very nice, in fact I've only once seen a rusty inside on my limo which had a cloth top that retained water. Painting the inside will give your arms good exercise but not much else.

To me Packard passed away in June 1956, what came out of South Bend were mere ghosts

All the testing in the world will not make this a Packard part.

Insufficient engine oiling was not a problem on V8's so the new pump has nothing in that realm to improve. Bearing life is long as long as oil is changed per recommendation.

The original pump has a design flaw caused by the addition of a vacuum pump. It puts a sideways thrust on the pump shaft which results in an ovaling of the hole, the result is that air is drawn in. This air wind up trapped in some/all lifters.

Bob, We should have one, will check on Wed. On the house.

Bend them and the weaker one is the front, same if you're colorblind or working outside at midnight.

The heavy duty version has same springs front and back.

Industry #'s front #122 orange, back #130 YELLOW

On the gear reduction starters it is often low voltage that causes that phenomenon. Does it crank well?? After starting is it that the starter keeps cranking or just stays engaged with the flywheel? Does removing one battery cable after starting fix the problem temporarily?

Ungainly body style w/ very tall windshield, Packard knew better. I'll speculate it was made from a car with a shot body.
Shipping over water is quite inexpensive

Does the starter keep cranking after you let up on the gas pedal(electrical problem) or does the bendix drive stay engaged after starting (mechanical problem)??

A design flaw caused the pump shaft hole to weaR TO AN OVAL SAHPE ALLOWING AIR TO BE SUCKED INTO THE PUMP AFTER THE OIL HEATED UP AND GOT THIN. oops!! It is not a pressure problem that causes the ticking, it's trapped air
