designing a frame/suspension

Im trying to design a frame/suspension for a final project in school. Im designing it mainly on Inventor, but also on autocad. My first question is, I want to base the frame design, which will be designed for a 94 burban that'll lay 24s, Im thinkin 3x3 .25 wall square tubing to start with. Im designing EVERYTHING for this and cant seem to find cutaway views or section views with measurements, if ya got sum, or know where I can get them, let me know please. any and all help is appriciated.

try a body shop with a frame measuring system, they could prolly get those for you

do your homework and do alittle research.   i googled it, and within like 3 minutes i had full frame sheets/pictures 

heres some prints for a 96 burban <img src="http://img27.imageshack.us/img27/2404/framenef.jpg"/><img src="http://img265.imageshack.us/img265/2972/bodyz.jpg"/>
