UEB bridge problems

hi all i'm looking for info on how to set the bridge on this EUB. It's not covered in the setup & repair forum.

Firstly a daft question about my bridge......I'm going to set it so the lowest side holds the treble strings, is this right?

The real question is when placing the bridge onto the body of the bass i don't have any f holes so I don't know exactly where to place the bridge.
How do I know if it's in the correct position for string length & tension?

Any suggestions?

all sorted now. the builder of this bass got in touch & sorted this one!!!!
