Pivots are easy. You should be able to nail a 360 once you get your basics down.
First off, you have to think of it as a forward motion, so do not start by backing your pony. Eventually, you'll want to right hind to stay planted, but when first starting to teach the pivot, just forget about what he is doing with the hind feet, that will come.
Turn like you are going to pivot and press or tap his shoulder until he crosses over. You want him to cross his left front leg in front of his right. Do not let him cross behind with that left front leg. If he steps forward to cross over, that is fine for now. Keep this up until he'll move away from you, crossover correctly and keep his body straight.
Then you can start watching the hide and trying for a step, then two, with the right hind planted. You just build from there. Make sure you aren't pulling him forward and out of the pivot or pushing him back into it.
Also, think about your set. Ideally, you want a two-step setup. It works well to just never move the right hind for the set. You set the left hind, then set the front. This will help you with your pivots.
