Well, I finally got my zipzap looking the way I wanted it. I never liked the original wheels or bodies as they didn't look 'right.' I had a few HO scale slot cars lying around and decided to try and retrofit some wheels and a body to my zip zap, while still being able to use the stock bodies. I had to trim the chassis in places and gut all of the stuff out of the inside of the HO body, shorten the hood to get the wheelbase right and had fun getting the front wheels to look right (now the back wheels look too big). But, it's a lot better than stock and it's pretty cool looking if I do say so myself. Check it out:
