Take the guitar a competant luthier and consult with them as to the best course of action.
Yeah, changing tuners isn't like changing strings. Any work done on a guitar, other than replacement copy saddles (don't modify original), should be done by someone with experience. Just like a car, if one has no mechanical ability/knowledge, they should take it to a mechanic. But, I would imagine that anyone seeking advice on guitar repairs has some experience doing their own guitar repairs.
Assuming the OP is capable
, replacing tuners is quite easy. Most important thing to watch for is proper alignment so that the rollers rest properly in the holes. If not placed just right, they will have too much friction (by not resting properly on edge on hole) and be difficult to turn (also won't be as smooth as the should be). As I mentioned in an earlier post I do recommend (even for the most experienced) to use the least invasive method available. By finding tuners that will fit without filling any of the original holes, the original tuners (or a replacement pair with original specs) can be put back on and guitar returned to it's original state. In my case I found ones that matched two of the old holes and one hole that was in a completely different spot (drilled new hole). For the one hole that was close enough to an old hole to require filling and drilling, I did nothing (3 screws hold the temporary tuners in place just fine). At any time tuners with the original specs can be put back on and the only evidence that it had ever been modified to accomodate new tuners will be a single tiny little hole underneath the plate.
Warning to the OP: You do only get one chance to install them correctly. And it is pretty easy to screw it up. If you do, you're only left with four solutions. First is to put old tuners back on and look for a replacement with orignal specs/spacing (best option at this point but only possible if you did the no drilling and filling minimally invasive method mentioned above). Second is to fill the new holes and drill them again (a pretty botched job). Third is, find other replacement tuners that have different spacing altogether so you can drill entirely new holes (also a botched job). Fourth is take it to David who has experience fixing botched tuner installations (best option if you already filled and drilled old holes).
NOTE: I'm assuming you know that you have to actually drill new holes for the mounting screws. If you were thinking to just screw them in (using the screws to drill) you should definitely take it to a luthier.
