Ok,

You can get them at A-Main hobbies etc.

The TRF 502X outdrives have a design flaw in that the slots in the oudrives extend into the gearboxes allowing dirt and dust to pass through the outdrive into the gearbox. What the Durango boots do is seal the slots so they are not open. They fit perfectly into the space between the plastic gearbox housing and the metal outdrive without disassembling the gearbox. It's a bit tricky when they are new.

A tip: The durango rubber is very durable, but can rip as you pull them over the "dog-bone" end of the outdrive. To install put the rubber outdrive boot onto a set of thin needle-nose pliers to expand the boot and allow you to slip the dog-bone end throught the hole.

The boots don't really wear-out on the in-board, and I have never had to replace them. They keep the grease in too. I tried the Durango boots as well on the outboard (wheel-side) but they did get torn and were more of a problem there. I also put these boots on my center drive-shaft just because.

Anyways.....buy a few sets (I think they are cheap) so you have spares.
