No, it's not that easy. The big issue is width. Kits made to bolt in to a Mustang are a bit wider than a Cobra kit. To solve that problem, FFR designed shorter arms and shorter axles.

Also, the Mustang is a Unibody. Although the pick and mounting points are the same, the design of the frame is very different.

FFR has a bolt in kit for their cars, but it's very different than what fits in a Mustang

It can be done, of course. But it won't be a simple bolt in operation.
