I want to know if the rear end used is same width as Cobra Jet. Mentioned are 15x10 rear wheels but are they the same 3.5”s of BS? I have a S197 and I would like to know details on the rear suspension and if/how does it differ than a Cobra Jet. Lastly is this ‘clone’ car able to compete in Cobra Jet competition? Also wonder how many Cobra Jets are built and raced that did not start as a non-VIN CJ. Thanks
