This brake plate appears on all FXST models from 1990-99. For pre-90 models, a number of different brake plate and master cylinder configurations were used. So this plate was designed specifically for the 1990-99 vintage. That being said, this plate will fit certainly fit the pre-'90 frames. However, master cylinder and reservoir configurations would need to be updated, when running this plate on those early model bikes.
Original wrinkle black finish is good, but it shows normal, light wear for this vintage. Plate is square condition with no evidence of twisting or distortions. And there are no cracks on any of the mount holes.
