That's what I was thinking off, the ones with the grooves all along the saddle? not sure if its just a case of swapping one straight in though?

I fitted one on one of my basses and it was a lovely straightforward swap, all screw holes lined up perfectly.
gjones's tip is certainly worth a try in the first instance, it wont cost and if it's only slightly out, it might well do the trick.
