I ended up having to easy out two bolts. One the torx was stripped, I drilled it and got the easy out to work it loose, but then broke it trying to get the bolt off the tool! Sears replaced it. Then i went after the snapped off bolt.
I wasn't quit centered with my drill and it tried to walk off the bolt. I removed the roll bar section and got better access. I was then able to drill back into it and miss the threads. after a couple days of penetrating oil it came out without too much trouble. Here it is all done.
Now it's new grade 8 hex bolts with some anti seize and the new sun visor hangers.
Thanks again for the help.
