I really appreciate everyone’s input. With any luck I’ll get a chance to start this weekend. I’ll report back when I have some news.

Garry: 
I had a similar situation with broken bolts on a Mustang (brother-in-law).  As Smitty said, the broken bolts aren't holding anything now.  They're not loaded by more than their threads.  Center punch one at a time and worry them out one at a time.  The Mustang's bolts took the better part of an afternoon, but they came out.  Best of luck.

Thanks Smitty,

The four bolts that broke off, broke as I was trying to remove them. They were extremely tight.  I fear they are either cross-threaded, or have been pounded back and forth so much that the threads are useless. Having never worked with a left-handed bit, how does this info play into the equation? They are broken beneath the surface, so grinding the slot is a no-go.

Smitty Says;  The bolts were under tensile stress only until the head or shanks broke off.  Now what remains is just a threaded dowel sitting in the hole.  Nothing holding it there but thread friction. It wouldn’t surprise me if you couldn’t press your thumb tightly against the stud and rotate it and unscrew the stud.  First thing I would do is use a Dremmel cutoff wheel and cut a slot in the end of the stud.  (If it is sticking out at least flush).  Then use a small screwdriver to turn it out.  Second best, go to a tool supply or on the net and buy a 1/8” or larger left hand twist drill.  Chuck it up in your reversible electric drill and I bet money the stud will come flying out before you can get  started into it.
