If you leave the tone knobs all the way up it doesn't really matter. Otherwise .022s will keep things above pure mud for more of the knobs' travel compared with .047s. My old Tele has a .01mfd tone cap, which is still pretty dark with the tone pot all the way down. Back in the day if Guild, Gibson, Fender, etc. ran out of a particular component they'd often just use something else to keep the production line moving.
