I have no idea if the gauges work and have no way to find out. I was told it came from a 1995 Dyna Glide. The chrome bracket is in very good condition and will fit other models and years but I do not know specifically which ones. The mounting brackets are standard Harley OEM size and distance. It does fit a 1999 sportster as I have tried that. 

No returns.

No guarantee on which bikes/models it will fit.
