Like Dave said build the funny car kit, you can do a lot of thing with it, some Braided Lines, Hex Fittings, i can show you how to make them out of some Alum. Tubes. Some wire out of old radio or VCRs and maybe some nuts and bolts from SCALE HARDWARD.
And on this site checkout Chris ( MOONEYZS ) on Drag Racing Models, 1/16 scale Army Vega Funny Car. Some great ideal and a super cool build.
Hope this help. AND HOPE YOU GET BETTER SOON. Have fun building.
