I'm looking for anything that could help me make a 3D model of a caterham or westfield nosecone. Anyone know where to look? The nosecone is one of those parts I really don't think I could make from scratch, so I figure the best alternative is to modify the chassis dimensions so that a caterham or westfield nosecond will fit...

Have a look at George Cushing's web pages. He has two different sets of plans (quite detailed) for nose cones.
