About a year or so ago, I swapped out the A5s in one of my PAF 36th sets for A4s. They were weak, which isn't surprising, but I wanted to give those a run.
Now I've got the pickups apart again, and wanted to de-air them, but leave the A4 magnets in.
The neck pickup went fine, the spacer bar fit, all is well. I ordered some 53mm spacer bars, and they don't fit a DiMarzio F-spaced pickup due to its 51.5mm spread (which I found out later).
So, where can I find spacer/keeper bars to fit? Find broken DiMarzios and scavenge the parts?
