It really depends on the size and shape of the existing hole in the neck. There are at least 3 different kinds of holes and matching tuner "splines".

There's a Grover type friction tuner that has a little screw sunk into the wood of the neck to prevent the tuner body from turning.

The geared 5th tuner often has a bunch of small splines plus one rather big "blade". These combine to hold the tuner in place against rotation.

The simplest kind of friction tuner just has a tapered brass collar, with very fine (if any) indentations in it. A good tight press fit is all that prevents it from rotating in use.

The diameter of the existing hole is probably the first key thing to figure out. Stewart MacDonald shows the dimensions of all their tuners, to help you choose which will fit best.

To illustrate, here's a Stew Mac geared 5th with splines and "blade".

This is the simplest friction 5th peg:

Here is the Grover "Perma Tension".  It is actually THREADED, which means the hole in the banjo neck is also threaded.  The little set screw is shown.

They don't make that anymore though it can still be found. The part number hasn't changed, however. The original  is my favorite for replacing Grover Sta-Tite friction pegs. Doesn't require reaming when replacing the Sta-Tite and the hold down screw uses the original hole. There is a little reaming and creating a pilot if replacing any other 5th friction peg.

There's a problem with the way Grover packaged them. The #2 wood screw they supplied is wrong which causes the worm and gear to be slightly misaligned and not turn smoothly.  No doubt, in one of the sales or management takeovers, the original spec was forgotten.

The correct screw is a #3 wood screw aka a Fender Jazzmaster pickup mounting screw. Those are a little long but cutting 1/4" from the end makes them perfect. Coat the non-threaded part with a light grease (this is important because that's a bearing surface). This will align the parts as designed and the result will be smooth and trouble free.

If anyone does have one of these uninstalled — or not working well, send me a message and I'll get a #3 screw to you in the mail. Outside of Fender, I don't know where to get them in small quantities — and what's the point when you need only one?
