BK, got back to me on this, so i'll post it here for others in case it helps.
BK recommendation: 0.022ufd for the bridge and 0.015ufd for the neck
i picked up a few pio's from aerovox 0.022uf, russian k40y-9 0.015 and sprague vit Q's, 0.022 & 0.015.
i'm just gonna hook em up via alligator clips and compare em to each other and the sozo's, etc. i'll reply back soon after i get my controls/pickguard setup.
