I'll give the one bolt option a shot and use the broken bolt as a guide pin as planned, assuming I can't get the bolt out. Thanks again!

That should work. The one bolt will hold it in place and you need the other one to prevent the entire block from rotating. Two problems can result. If the block moves down it the sensors can hit the tabs on the flywheel. Or it can move up and be too far away for the sensors to work.

That's a big help! Thanks!

Yes, I the bracket is #12 in the diagram and the bolt (#14 in the diagram) is broken off in the block. I'll try and extract it, but I'm 99% sure it isn't going to come out without drilling it out. I also had some H2O pump bolts broken off, too, that required drilling on Friday.

Looking at the diagram again, I see the same thing I saw at arnnworx.com/sensor_tool.htm (see attached photos I stole from him). In the dc diagram, it shows a 3rd sensor (dia #24, reference sender/timing mark sender) going through a 3rd hole in the bracket. However, the bracket I have does NOT have that lower part (circled in attached photo). Is this a model year thing? Or is that probably broken off my bracket?

That third hole is for another sensor that hooks up to external diagnostics. I think I tossed mine because the cable was frayed. You don't need to it to run for sure.
