In need of a replacement bridge and a wiring schematic for an Electra Westone Spectrum Phoenix

I have an Electra Westone Spectrum Phoenix Bass, I think its a 1983, that I need a replacement bridge for. I'm having a hard time finding a 7 bolt bridge in the dimensions needed to fit the footprint of the old one. The bridge dimensions are 82mm x 52mm. All the ones I'm finding are to small. The original one was black but I'm looking for a chrome one if possible, but at this point just finding one that will fit is a luxury. I'm also looking for a wiring schematic. Any help is very much appreciated.

Hi and welcome here.

Can't help with the bridge but we do have a schematic on our website which might help steer you in the right direction:

I've seen this schematic but its not the right components. Mine has a 3 way toggle box switch with P/J pickups, 3 pots which I think are 2 volumes 1 tone (because only 1 pot has a capacitor) and an on/on toggle next to the top volume pot which I'm not sure of its function.

If you haven't already, you might try looking in the Electra Forum too: LINK
