Welcome!
I know I've seen them somewhere so I'll search for them. If I may make a suggestion, it would be to make pre-1983. turbo car - ground effect turbo car. So,technical regulations from 1982. would be perfect.
Please, update us on your work, I was always intrigued about how would those cars look today if developed with CAD and CFD.
In the meantime, try obtaining technical regulations from FIA Historic Formula One Championship site contact page

BUT (big one), it would be great if you could design an 1982 car using 2010 safety regulations (survival cell dimensions etc.), while maintaining all performance-wise regulations from that time. That would be great. So, 2m wide cars, rear tyres limited to 600mm, ground effect, movable skirts and all that was banned in the meantime.
