Trying to find out what options are available,should I ever have need or desire to change out the stock Steinbergers....I'm looking for whatever would be closest to a direct swap (ie: not enlarging or having to "dowel" present holes)....someone mentioned that the Steinberger holes were 10mm & when I asked WD about their offerings,they said that their repro Firebird(banjo) tuners were 10mm & that if the Steinbergers were indeed 10mm,I'd only have to drill holes for the 2 mounting screws per tuner...Any thoughts or verification ???
