The hardest part about all of this was finding the conical washer,which my forklift guy called a "thimble." I found something online at AutoZone and they were calling it a cylinder head washer. Went to my preferred parts store, which is NOT AutoZone, and they had what I needed.
Heated each bore with MAPP gas, about 30 seconds apiece, did that twice. Quick shot of penetrant and popped a transfer punch in there. Left hand drill, and they came out like butter.
I did notice one of the bolts that I removed that hadn't broken was much shorter, and that bore appeared to have been filled with a weld. I plan to remove both hubs in the future to service the brakes, so I'll address that on the drill press.
I appreciate everyone's help with this, I look forward to trying those rods someday.
