FMC Dimensions?

Hi everyone. I haven't posted in quite a while. I got really busy with school. Now my 6th hour is all about designing whatever I feel like :) So I wanted to know if anyone had detailed dimensions for a 737 FMC? I have the basic dimensions, but I want the dimensions for the screen and the keys too and I can't seem to find them anywhere. Thanks for any help guys!

step 1) download a 737 cockpit poster
step 2) use basic dimensions to calculate scale factor
step 3) measure all the dimensions you need en multiply them by scale factor
that's all! :-)
