Hey, i dont own this one yet, but i have the chance to pick it up. Just wondering what the specs were on one of these bad boys.. maybe the int. and ext. got changed over the years or maybe they transplanted the 4 banger in later cuz the orig. engine kicked the bucket... what is the breakdown of the VIN and how do I tell if it is an orig. cobraII or a 4 cyl.?? please help
