I should have updated this a while back but got side tracked.
We did go for the Hipshot bridge and it went straight on without a problem. Looks good too. I did a basic setup , intonation, action etc and it plays really well. I will try and get some pics when he brings it back. I got some CTS pots for him and he wanted to put them in himself.
I've told him that it could probably do with a fret level and, nut adjustment (its been loose at some stage and someone has done a rough job of gluing it back on.
