The Kellison Stallion became the West Coast Cobra some time in the early '80s. I can find no photos of the Stallion frame but, based upon various descriptions, it would appear the West Coast Cobra frame is a continuation of the one developed by Kellison.

As I posted earlier in this thread, I haven't been able to find any photos of the Butler frame, but the photo I was able to track down of the Arntz frame (Which Goodyears are these (Arntz from 1980 Hot Rod pics)) showed a ladder design. I have no idea whether the Butler is similar to the Arntz - perhaps somebody with some knowledge can help with this.

You can see the frame / chassis used in the West Coast Cobras (and presumably Kellison Stallion) here, and it's much different than the Arntz frame: http://www.cobrakit.com/Chassis/Chassis03-900.jpg

• Comments about the frame, body alterations, doorbars for protection, sale of the company and West Coast Cobra: Kellison Kit Cars - Kit Car History - Kit Car Magazine

So, we have photos of the Arntz and WCC frames, but not those of Butler or Kellison. IF the Butler was similar to the Arntz and the Kellison similar to the WCC, there are many differences. IF the Butler was significantly different than the Arntz it could be much closer in design, but until someone can produce more information about the Butler frame (including photos), it's still an open question. In order to answer your question accurately we should have more information about the Stallion as well.
