Finished this the other day for the Cannonball CBP. Its an AMT 3N1 57 Fairlane that I found in a discount store still sealed for $10.
I went for a stripped down,no frills, lived a rough life, bad as you wanna be street racer look from that era. Removed the body trim, drilled trim mount holes then filled them in with intentionally bad body work. Scratch built a few pieces....really big gas tank, rollbar, seat mount, hood scoop, exhaust, supercharger plumbing and air intake, rad hose (because the only one it had was on the intstruction sheet) added a straight axle front and a few other things that I cant think of right now. Put a coat of semi gloss clear over hot rod grey primer and a flat black hood. Threw a few spares in the back and some borrowed license plates to help out with getting across the country and then hit the road in a race car thats got no problem fighting dirty.
