I purchased my E-M Cobra kit in September 1995. I do not know which type it is, but I think the tooling for the body was relatively new at that time. It was built before the chassis and body were stretched. It still had the 90" wheelbase.
My body and frame each has a unique number plate. The body plate is EM4427SCxxxxxx1995, and the frame plate is EM427SFxxxxxx1995. As you see, both plates end in 1995, which coincide with the build year. I always assumed that was the case.
There is a history page on their website.
