I was very unsure of the c-c dimension of bridges, they all seem to differ slightly and 74 mm isn't 74, but 73,8 and what not. I took a chance though.
This was a spot on fit for my Epiphone Les Paul Prophecy, using the existing posts. Easy to file away material for the string grooves and the bridge handles B-standard intonation using 056 low end string without any hassle with lots of adjustment possibility left. Easy to adjust, rattle free. A good upgrade from the original bridge with the wire locking that could not even keep the saddles down.
The posts were of a smaller diameter than my Epiphones holes, but that's my problem because i pretty much intended to use the bridge only so i never measured it.
