Im thinking about adding a bigsby vibrato on my SG down the road, and im just kinda doing some research.

And from what I can tell, a locking roller bridge trem is one of the best things that you can get with a trem, or vibrato unit. And I found this one on stewmac

http://www.stewmac.com/shop/Bridges,_tailpieces/Electric_guitar,_Tune-o-matic_bridges/Locking_Roller_Bridge.html

but I have no idea if it will fit. Most importantly are the post distances. Some of them, as compared with some of the tunomatic bridges on stewmac have slightly different sizes, and apparently their are different threadings for the post.

Any ideas or suggestion on how to find out if it will fit my guitar?
