According to the Nu-Rex instruction sheet "the total range of steering column spark control is approximately 40* of crankshaft travel". Why am I having 50* of travel?

Look at his distributor body. Look at the slot where the upper plate arm swings back and forth as you advance/retard the spark lever. Compare it to another known good body. It is this slot that actually limits the total change in the spark advance. If this cap has been modified, you can get more total advance than 40*.
That's all I can think of. Maybe swap in another distributor body as a test. You really should not be getting more than 40* change from "up" to "down".
