I remember measuring my 100's and is the same as the Gotoh 510 tremolo.
don't have the sterling 100D anymore but you can google the specs for the Gotoh
Thank you sir.. I used to have a Older EBMM JP6 and an SBMM JP100 & JB70 and just been missing out on having those. I always wanted to swap the bridge out on an SBMM and see how well it does.
