DIY Degree Wheel

Just buy the cheapest generic (i.e., Chebby) degree wheel you can find and drill out the center hole to fit the Olds crank bolt. That's all Mondello does for his high dollar "Oldsmobile" degree wheels. They even still have the Chevy three bolt pattern for the balancer on them.

I made one once that I printed on a CD label.
As far as the 5 11/16" thing goes, this is one case where size doesn't matter.
Print it out as big or as small as you want. The angular relationships won't change (it's a geometry thing).

Ah, but it DOES. The angles may not change, but on a larger diameter wheel the degree marks are farther apart at the circumference and thus much easier to read. The larger wheel will make it easier to get a precise reading of the angle. Note that pro engine builders use a very large wheel and a pointer made up from a bent piece of welding rod or something similar.

Whatever size is easiest to use is the best for you to make it. It will remain accurate.

Printer distortion may bump it a half a degree or so, but not enough to matter, and you can see any distortion, because the divisions will be different sizes (you can check divisions in different portions of the circle with a pair of dividers if you want to be absolutely sure they're equal).
I'd call it a matter of diminishing marginal returns: You can get pretty darn close for free. If you want to get a little bit closer, that'll cost you 20 to 50 bucks more.
