So I had this really weird single tree on my cart, kind of roller bolt style? That does not really work with any traces. So I made adapters for it from leather and rubber washer for extra safety. It worked okay… but I wanted to do better. So I looked everywhere and took so many measurements to try to find a singletree to fit the existing holes on the bracket. Finally got a great one from Kingston and managed to switch it by myself! So proud as I am pretty clueless with stuff like that.
