[the shadow]

my question is are there any changes or updates that would need to be made to a superformance cobra from the late 90's as compared to a more current one, did any problems manifest that they have now rectified or is it all the same as todays chassis's .I believe the car number I was looking at is in the 330's with around 15K miles on the chassis -SP square tube chassis (newer engine). I know on other posts I have seen talk about different years introducing needed updates and if the older models could even be updated. I'm guessing suspension ,brakes ?
