Yamaha Attitude Custom needs a bridge...help!

1990 Yamaha Attitude Custom (brother to the Billy Sheehan Yamaha Attitude LTD v1 bass).
There is a Dimarzio X2N-B humbucker woofer pickup right at the heel of the neck and hidden under the pickguard.
Middle pickup is a normal Split P pickup with brass plates under them like Fender does.
Then there is a Piezo pickup on each saddle.


If anybody knows where to get a replacement Yamaha Attitude LTD (version 1) bridge or (or saddles) please clue me in.
It's the same bridge that was on the Billy Sheehan Attitude LTD (version 1).
I would like to remove the Piezos in my bridge, don't need them, just want the Split P and the Woofer Humbucker like the Attitude LTD has.
This bass is constructed just like the Attitude LTD was except the bridge saddles, so a bridge without Piezos will mount up perfectly.
If I can't find the Yamaha bridge or saddles, I need to decide what bridge makes sense to be not interfering with the four mounting holes already in the bass.
Thanks for any feedback and suggestions.
