Getting Started on CRJ 200!

CRJ200
TO ANY ONE WHO CAN HELP!!!!

For a while now I was browsing and checking out everybody's sims and virtual cockpits. More I've learned about the home built's the more i wanted to build one for myself. I just throw this question to anyone who can help and been there and done that before. I am looking in creating a crj 200 sim but it is kind of hard to find a generel dimesnions of mip' etc, overhead,central pedestral and all that good technical drawings that would be very helpful to make one up. I could make the drawings but I need a general dimensions of those panels. Any researchers out there or whom ever can help me started I would appreciate! Also can someone can pinpoint where I can find used cockpit parts!!!!

HELP!!!!!!!!!
