Oil pump assy for slant 6

I just took my 64 completely apart a couple weeks ago for cleaning and inspection. It's really simple. I used the info in a 68 FSM to check for wear and it passed every measurement. The pump has 97K on it and in spite of a little grooving on the inside of the lobes it's going back on the 225. All the talk about replacement pump gears failing spooked me. I think I'll install an oil pressure gauge though to keep an eye on it.
