I've been reading rumors that a large clamp tremol-no won't fit my Tremonti SE Custom without filling the trem claw holes and re-drilling (but it seems that also goes for any newer model, '12 or '13). I really wanted to install this soon, and I thought it was a drop in replacement. Can anyone say for sure that they won't fit? And this also means that the US trem system won't fit without drilling, right?

I like easy upgrades!
