Hey folks, I have an early 80s Special II. I'm getting a Bigsby B5 for it. What do you folks say is an optimal placement for it? It already has a roller bridge. I was planning on going to a store and take a few measurements to see what the manufacturers did. Also, the unit I'm getting doesn't have a spring so I have to get one separate. What's the thoughts on that? 1" or 7/8ths?
