Beware of the older locking Grovers that do not have the thumb wheel. The posts are extra long and tend to look disproportionate sticking out of the headstock. The internal locking cam also isn't the best and can sometimes lose its grip when tuning down even as little as half a turn. The newer style with the Sperzel-like thumb wheel are much better.
Made by Gotoh, not sure if they'll fit. And if you're set on the regular Grover Rotomatic locking tuners, I have a spare set I'll make you a deal on, I'll never use them.I can't seem to find them with keystone knobs though rather than the kidney-bean style.
The new thumb wheel versions came on my new LP Trad Pro and I like them a lot. And they also very much retain the traditional Grover look. The only reason I didn't buy them for my V projects was they are pretty new tuners so they aren't floating around used and new they are like $80!! I got the Sperzels for $49 new.I didn't even think about maybe just swapping out the knobs... maybe I'll order the Grovers (with the thumb wheel) and deal with the knob change later...
