For me, one of the best sites DIY a B737 cockpit. So before you start building anything, visit Karl Clarke's website. Beautiful videos, very detailed plans, a wonderful job.

Spanish cockpit builders are amazing people. First, they got together, and are in contact close with each other others through a Forum extremely interesting. They have so far organized eight meetings national where each of the participants brought their works, ideas and his questions. And, at instead of solving their problems with packages of Dollars, they share the work according to the skills of each. This is how that they have homemade dashboard panels, instruments replacing Project Magenta, and all this free of course. And this is also how was born the IOCards project this is the system I chose for my project. Manual Vélez designed a set of interface cards. Go to this site without further ado! ( It's a of my favorite sites)
           

The Clement Stals site in Belgium in Dutch of excellent quality. Another very meticulous B737 cockpit builder in everything he realize, see his cockpit more real than the real one!

A another site in Belgium in French, and on the Meticulous side, it is the top! Definitely a small country but with great Gentlemen like Rudy Danese.
