I've made maybe, three or four SM's, SM 2005, SM 77' and Rockin Space Mountain, and still have yet to make one with Mattatt14's scenery. But I am making one, but probably just put the video up on youtube. Anywho..
Well this looks very accurate as far as I can tell. But just as a reference go to this site

scroll down and look for space mountain. They've got some good layouts, just in case. Good luck :-)
