Mike (site owner) has
several different mounts in his store depending on what vehicle you have, and he is creating more all the time.
He also does custom jobs on request, but those take understandably longer to do. He did one for me (Hyper 8) - I sent the whole buggy to him so he could test fit as he went along. Mike's stuff is top-notch; you won't be disappointed.
There is no comprehensive listing of all the conversions here, but if you dig around, I'm sure you'll find many of them.
If you're new to the brushless scene, you might want to check out
Serum's information thread; it has a lot of useful information. And to do what-if scenarios for various gearing on a specific vehicle, you can try
this page out.
Feel free to ask questions, that's what we're here for. :)
