Just wanted to say I have this cover on my car, and I think I paid about twice as much as you're asking. The install was straightforward, it looks good, presumably helps with heat, and makes it very easy to drain the diff fluid in the future. If anyone is considering changing their diff fluid, I recommend picking one of these up!
