Broken Motor Mount bolts (in case) removal
Hit a pothole this morning and, somewhat long story short, all three bolts that hold the right motor mount to the block are now sheared off. Suspect one or two were already broken and finally snapped the last one. Clutch fan is hitting the frame rail when I turn left. Limped it home with flashers on.
My problem now is getting the broken bolts out of the case. I was able to grab one enough with locking pliers to get it out but the other two broke completely flush. I can't seem to fit even a small right angle drill to pilot for a bolt extractor, frame rail blocks my access. I was thinking I could drill into them at an angle and then use the drill bit to wrench them out, but I fear the mess that would be left if it didn't work out.
Anyone ever run into this and come up with a clever solution short of pulling the engine?

Yes I realized rather quickly thereafter the plethora of info out there! Sorry for jumping the gun.
So enjoy this pic of a very cool RHD XJ I recently saw out on the road ...

I used Brown Dog motor mount brackets and didn't touch the three snapped bosses in the block. I've seen that somebody else makes brackets that are shaped a little differently and painted black.
I recommend this rout because it seems more long term than re-using three points of failure.
