Good source for 52mm humbucker bobbins

[copperheadroads]

I'm looking for a good source for 52mm humbucker bobbins with more of the PAF dimensions .most of the 52mm bobbins i've tried have small slug holes & they have cracked when i potted them . I have been using with the Mojotone 53mm stuff & i see more 52mm parts that I want to try but the bobbins have been what I've struggled with .
