I'm working on a guitar project this summer, I'll have photos when its done

, but I wanted to put in a Mosrite pickup into the guitar as well as maybe a tremelo setup. I was curious what the measurements height wise on the typical Mosrite pickup are? It will be standing on the body and not with a hole inside. Also how hard are tremelo units to setup and how big are the units themselves? Is there alot of their setup inside the body. I'm debating adding one because I don't think it would look good on what I'm making so I'll probably stick with the just the pickup. If anyone has or could get some measurements on one for me that'd be great since I don't have one myself

Much thanks for any help guys!
