Need some setup advice for USA Soloist

[Acapulco Gold]

I have a '86 soloist that came with some setup issues that I didn't address as first because it was my first floyd shredder guitar. When I set about to set it up, it got worse. I straightened the neck which was bowed, and got it to 0.010 but then both the A and E buzzed open. I put relief back into it and it's ok now, and I can lower the bridge to normal levels.

The A string is lower than the E, how can I shim it so that it's equal or higher?
Mine has EMG's, but it's pretty tight in the control cavity. Do I have any hope doing an 18v mod without digging holes in the guitar?
Thank you

Take your saddles off and look on the back. There should be 3 sets of corresponding numbers to make them go in an arc. I forget the numbers offhand, but the E strings are the lowest with the A and B higher, then the D and G the highest. You can also put copper tape underneath as shims, or they do make metal Floyd saddle shims if you need them more leveled out.

depending on what saddles are on it - it may be numbered
blank, I, II


as to the 18v
jackson has used the same control panel for years. 18v will fit.
