I used my cut off wheel on my die grinder and cut the cast off splinted my wrist with paint sticks and electrical tape and called it good! I probably am using my wrist more than I should but it doesn't hurt much so I figure I am good.
When I am not in the shop I just use ace wrap to give it a little support. The paint on the interior turned out great! I got the steering column installed, windshield wiper linkages and motor installed, and the clutch linkage painted and partially installed. Pics will come when I find my camera, cant figure out where I set the thing down!
