Your SB-900 Black n' Gold is certainly the oddity. Narrow spacing, I presume? The SB Black n' Gold I and II as more commonly known were the same as the SB-R60/80 and the Elite I/II models. Just different hardware colours and paint schemes. I will certainly sort you out with a new bridge for the BnG in the narrow spacing as soon as numbers are in at the end of April. I need a minimum number of people interested in repro hardware to justify the initial equipment outlay. I'll talk by PM more on this of course.
The neck with the crack....which bass is that? It looks like it is following a very strange line and does not look like an easy repair. How is it structurally? If I were repairing it, I would drop a couple of Maple fillets in there to strengthen it....the crack is dangerously close to being cross grain crack which is the weakest glue joint to make structurally. You need to put that into the hands of somebody who knows what they're doing with the repair. If they don't crack the whole thing right off and suggest wicking glue into the join, take your instrument and go elsewhere.
Nowhere close to Finland, are you?
