+1; just put the 62 RI in my no-name fake P bass. Fender really nailed it with this pickup, and on sale it's only about $60.
I've had luck with a tip from another TB'er; went with a 250K volume but a 500K tone pot. I forget what Duncan recommends for the QP, but it will be on their website in the wiring diagrams.
I think the "metric" may refer to pot shaft diameter; Alpha pots are slightly off in size from the 1/4" shafts on CTS or Bourns pots. No big deal either way; on a P-bass, you may have to ever-so-slightly enlarge the holes on your pickguard.
Man, I'm happy for you. I've re-built about 5 instruments and I'm hooked. Let us know how it comes out!
