FF chassis/body distinctions if any

[the shadow]

thanks for the responses, I have been a cobra adnorer for over 30 years and have vowed to make this year the year I get one and ditch the C3 corvette (which was also a bucket list car) that I have a love hate relationship with due to its inherent design flaws for servicing parts. In a perfect world and time I was hoping to score a used Superformance after selling a few toys (race cars) but due to the covid and the economy no less then 6 buyers have bailed due to funding. so I decided to try to score a much more affordable used FF cobra. I do like them I just seem to be finding a lot of Mrk I and II's and want to know if they are updatable or whats "bad" about them if I end up with one. Like I stated before the one thing I think the FF's dont have is that nice hood/cowl bow in the middle, they seem flat and the roll bar is too narrow and too tall for my taste. I appreciate the input from the forum.
