I agree with Randall and Tom, except I will go one step further. Randall says "almost certainly" and I will say absolutely your car has been modified. I owned a TR3B and did a lot of research on what was different and what was the same on the TR3 and the B. As to the dash the only changes that I recall are the positioning of the speedo and tach. On early cars the speedo was on the left and later cars they were swapped in position, this happened before the TR3A. The other item, was one I never got a clear time change on was that the center plate where the guages are mounted on a few very early cars was covered with vinyl and on all later cars was painted in wrinkle paint.
