I too, bought mine new back in the day form Sears. It has never been dropped. It has spent most of it's time a the drawer. It seems to work as it should, except for the reading of 1 1/2" off on the pulley, yet the car runs great.
I did a simple compression check, with my finger over the compression gauge hose, and the top of the stroke aligns with the roter on plug #1.
I can give it a try on the 1970 Cougar that belongs to my wife.
