I expect the body holes are drilled for a Fender ashtray bridge. Those more modern six-saddle ones are a bit longer. Fancy going traditional?

I wouldn't go too much by factory spec set-ups as they aren't the optimal set-up for low action. They are a spec which means that they won't have problems with the odd high fret and badly adjusted truss rod. But it's only a starting point and you can always take things lower with a proper full set-up.
