I don't know. I've used the Vibramates for all my guitars that have Bigsbys. It seems that the 72 reissue is the worst to put one on if you don't want it to look like hell. If you have gotten something like the 69 Reissue, then the have a vibramate for that, but I only used those because If I want to put the stopbar back on, then it's a simple fix. Let us know how it works out for you.
looks like in general it will take some work, either on the end of filing (or drilling) down a bridge for the strings to go through, or drilling new holes in the body for a different bridge altogether (i've seen a lot of people using Mustang bridges with bigsby's). looks like i'll go with the 1st option in case i want to re sell.
