Your paint is fantastic as well as the bare metal foil trim. Not to be rude, but with your black and white interior, the vented kick panels should be black with the grill in gloss black. The window knobs should be a clear color, they turned yellow after time. The bottom of the arm rest is chrome too. 25 years restoring chevy's gave me this info.
This model was a enclosed body. It had a non opening hood on the front area. It also had oval windows on the rear doors. I believe the box art showed white outline pin striping around the body. Don't remember the wheels but I know it had bigs n littles
There was a C cab hot rod model, that had an early Corvair engine. It also had the upper cross member, springs and lower control arms. It also had the swing arm axles as well. I had one many many years ago. I know it was molded in red and was 1:25 scale. I would love it if they actually made a separate front suspension for the late models. The front cover assembly on the rear of the engine, is to say the least completely wrong as well . The oil filter never sat next to the crank pulley but instead in front of the pulley. The oil cooler sat higher under the alternator. The engine is also missing the sides, front and rear shrouding. I have a 1965 Corsa kit, nobody mentioned it came with 13" Cragar S/S mag wheels. The Anson Sprint slots came in the later kits.
