The original wheels on this model were different diameters on the front and back. Because of this I never found any good replacement wheels that I liked. The fronts were pretty chewed up on the original so they were replaced with new wheels from my parts box. The original rears went back on the chassis.
Both sets got a touch-up with silver paint. The original exhaust ports were broken on this model when I got it, so they where were replaced with 3/32 acrylic tube that was heated and formed with a nice bend to bear some resemblance to the research photos. The engine components were primed and repainted.
A new windshield was cut from clear acrylic sheet, was formed and mounted to the raised posts on the underside of the body like the original. The body posts were drilled and tapped to receive stainless steel 2-56 UNC screws in place of the original rivets to mount the chassis.
