I was looking for locking tuners and found similar shape at Kiesel. The guys at Kiesel said that it might not fit as they don't have experience with it.
I have ordered one tuner for test and fits right in with no drilling modification or anything.
the center pole (hope that it is the right term in English) is about 2 mm shorter than the tuners i have but i don't think that it is a problem.
it is US made and 19:1 ratio.
just to make sure that the new low height tuners would be OK i have ordered also tusq nut ned-w-cort
it is 12" radius so, i think it should fit better than Fender nut. I did not get the nut or the whole set of 6 tuners yet, i have only pictures of the single tuner installed. Please tell me because I already had a bad experience in the selection tuner for 6.4 powerstroke
