Does anyone have any experience with the Advance Adapters 4.7:1 gear set? The splines on the input gear in my T-case are pretty worn and I am thinking of replacing the input gear. This pretty much means buying a whole new gear set. Unfortunately, Marlin's gear sets are never in stock and I'm beginning to think they never will be. I also hate the idea of buying Trail-gear.
Poking around looking at Atlas T-cases I saw that Advance Adapters offers a 4.7:1 low range set that is made by Sumo Gear (Toyota's OEM supplier, according to them). Anyone run them? Know anything about them? I really can't afford an Atlas and Marlin Crawler gears seem to be made of unobtanium.
