Does anyone know where I can find installation instructions to install shoulder belts? I bought some from Alan with the parted out M20C. These look like they have a clamp that goes around the steel roll cage. Or does anyone have any pictures? These are not the inertia reels.

Here is the clamp installed on the LH side. it fits over the tube, and under the skin. Real small clearances there. The LH side is a real bear to force in there, it took some filing on the clamp and bending it a bit, I finally drove it in. the RH side goes in pretty easy.

 

Alpha aviation has the instructions on their site

These are the genuine mooney upgrade ..... When you get the clamp around the tube , you should drill a small hole and put a screw in it so it cant rotate or slide......

When I dogged down that clamp, you could lift the airplane with it and it wouldn't move. You can drill a hole in the clamp, but I dont know if you can drill a hole in the tubular structure of the airplane without a DAR or Mooney engineering blessing.

Take a look at any mooney cage , They have hundreds of screws protruding in them...

Correct !  :D 

That is correct, and Mooney engineering has them all in the drawings. That spar has plenty of holes in it, but put a #30 drill but through the center spar and ask them about that.

"The Don" has photos of a Mooney where that was done--was not pretty, safe or legal.

If one were to be involved in an accident violent enough to slip/rotate the clamp and bend the attaching bolt to the point of breaking I would have very serious doubts that it would be a survivable impact. I would get written approval before drilling in,to any structural component. I don't like surprises.
