B5 is the one most often used, but there's one specifically for telecaster (looks dumb though)
You can do it yourself if you have a drill press and you're accurate, all you need to do is drill four holes. The harder part is considering the bridge. Most of the time when you put a bigsby on a tele, the whole bridge configuration changes.
The bridge plate changes to a flat one with different cutouts for the new actual bridge you need, usually a mustang/jaguar bridge, which requires that studs be put in the body (THAT is more of a pro job.)
There's also the method of cutting slots in the back side of your existing bridge where the strings would go, so that they can hit the saddles. This works best with a vintage style tele bridge (3 saddles)
Good luck!
