finding the hydraulic master for the clutch isn't a big deal- Try speedway motors.com. I got one for about $50. Mounting it is the trick. I went to a metal working shop and had them drill three holes in a piece of plate steel to match the mating/mounting surface of the master cylinder. Then I cut and welded the rest at home. If you can't do that, you can build your mount from cardboard and take it to a metalworking shop and they'll put it together for you for pretty cheap. Lots cheaper than paying someone else to do the measuring, make the cardboard mock up, have it fabed and then bolt it in.
