I have a right side footpeg assy including bracket and brake lever for something of that era. It is a steel brake lever so I think either YZ125G, YZ125H or perhaps even IT175G/H I dont know for sure what the exact fit is but I have always believed it to be from one of the models I mentioned. Maybe take the measurement between the bolt holes including the off set and I will measure it up to see if it might fit for you.
