Kit Cars at the Challenge?

NMNA - was this called a Tri-Hawk?

In reply to 914Driver :

Has to be based off a four wheel production vehicle for the Challenge.

So, two motorcycles 

In reply to 914Driver :

Tri-Magnum (one of the pix shows the drawing w/ title block)

The Trihawk 304 was FWD using a Citroen air-cooled flat-4, IDK if there are any others (edit to add link to a PDF of 1982 R&T article on the Trihawk).

You mean like a Bradley GT.   

In reply to Noddaz :

Either the frame or body need to be from a production four wheel vehicle. So yes a Mercury Grand Marquis frame with a Bradley GT body on top counts. Not sure if the rules allow you to drop to 3 wheels. 
 

So if you see a cheap go cart, I have a triumph frame I'm willing to sacrifice.
