Change oil pump while replacing pan gasket

I dropped my pan to replace the rear main on my 340. Thought about replacing the oil pump while I had everything apart, opted not to because the oil pressure had been good. Figured I'd save a few bucks. Literally 2 days after I bolted everything back together and fired it up, my oil pump failed. Same thing when I pulled my transmission to replace the leaking seals and TQ. Considered rebuilding it when it was out, but hey it was working great. Two months later I found a load of clutch material that clogged my filter. Soooo it's coming back out.

Murphy's law? Maybe. But I've come the the realization on this old car that, the time to replace these hard to get at parts is when they are easily accessible.
