This may or may not be a complete list; it contains the information I have been able to find.

DART (Scale Racing Products Incorporated) advertised in the major slot car magazines in 1965, claiming to be "the new standard of quality in slot racing bodies - with sales far exceeding expectations". Ummm... Whose expectations? In 1965 I was a teenager interested in (among other things) building and racing slot cars - what did I care about "sales far exceeding expectations"? I wanted lower, wider and lighter...
With such an enlightened comprehension of their retail marketplace, and the expectations of their teenage and young adult customers, DART's new standard of quality faded away pretty quickly. I have yet to find a single photo of a DART body.
Here is one of their ads:
