Pump bolts are all started and loose, prying the engine around with a pry bar but so far no luck starting a thread on those two bottom bolts.

JFYI, the outside diameter of the '50-'53 Ford/Merc driver's side narrow belt pulley is +/- 4.1", while the passenger side is +/- 4 3/4". The larger diameter crank pulley drives the larger ds pump pulley, and the smaller crank drives the smaller ps pump, so both pumps will run the same rpm.
