Thanks Muley.
Your rivets look correctly located.

I need to find my protractor.....

Measured mine.
My rivet holes aren't placed correctly.
I measure them to be 1/2-inch not far enough clockwise.
Which is the same distance that the timing hole on the flip side is away from being correctly aligned with the notch.

Now I'm really leaning towards a government reject part.
Although I suppose it could be a poor repop.

It's otherwise nice and solid.
I'm thinking it'll be good to use. How far out of balance could it be?
Would a few ounces lead to engine problems? Can't imagine it would, but asking the experts....

When I had my L134 at the machine shop they balanced the rotating mass (crank, connecting rods, flywheel, pressure plate).

Bought a good take-off pulley from MWM.
It has the timing mark notch, but no hole.
