Ok, Thank you, Barrie. I picked up a complete brake caliper assembly at the NHSA snowmobile swap meet today. I had to take a complete Bombardier chain case with secondary clutch to get it, but $15 was too good to pass up. I checked it and the bolt spacing is the same, so all I have to do is reverse the arm, and I'll be set.
Now, when the chassis comes back, I'll be ready to paint and assemble, then its on to the motor and finishing up.
OH yeah, I do still need to build a set of skis. I don't want to be running around on water skis, it makes the trails to mushy.
