Hi Steve,
Here's the details I found in the instrument file for your bass:
top: Bird's-eye Maple
accent: Purpleheart pinstripe
body: Mahogany
neck: 3-piece Maple
scale: 34" long
fingerboard: Ebony
pickups: Alembic MXY4
controls: volume, pan, bass, treble, mono output
originally made for: Music Unlimited, San Leandro, CAbirthday: February 6, 1995
This fingerboard is 1.65 x 2.35 (nut x 24th fret), it's likely that your Spoiler was 1.75 x 2.25, so the nut on the Spoiler would have been wider and the bridge spacing much closer. We have changed our default edge spacing (distance from the edge of the outside string to the edge of the fingerboard) to be .15 inches. Previously it was less so it was easier to bend strings right off the fingerboard. If you even run across another old Spoiler with that issue, a newly fitted nut and bridge saddles can tighten up the spacing and the strings away from the edge no problem!
