There are a number of very subtle but different things about a 4A verses a 4. I saw a "mixed " car at VTR this year. The commission number said TR4 but the body said TR4A. After looking the car over a bit, I finally found the owner and ask him what was up. Turned out that he had two cars and decided to use the parts of the two cars to make one and selected the features that he wanted. The result was a "mixed " car.
If you are inerested in just what you have give me a reply and I will give you several things to look for that should define what main body and frame you have. Remember that the fenders can easily be changed between the two cars.
