Realise I was a bit foolish filling those holes in. Measured the bridges with the callipers and I think the Wilkinson bridge saddles are 3.6mm lower than than the tune o matic. Thought about putting a sheet under bridge to raise it and could use same material I am using for the pick up rings but might just look really strange given how thick it would have to be. Does anyone know of any alternatives or is going to be drilling the holes for the tune o matic back out!
