Drill a pilot hole in the bolt, then use an E-Z out to extract it. Also called broken bolt extractors. Use copious amounts ob PB Blaster before proceedure.

My did the same thing when I took it off for paint. I could never get my out. I welded studs and used nuts to fasten.

what about welding another bolt to the flush mounted broke off one? Just using the one you just welded as the extractor.

Left handed or reverse drill bits, sometimes they back the broken bolt out, if not you just keep drilling, go next size up and redrill then retap..
Oh, before you start drilling, use a center punch, center punch the broken bolt good and hard, many times it will break some of the rust and let the PB get in better.
Pretty much all my drill bits are reverse bits, they drill holes just as good as a forward bit and act as broken screw extractors sometimes as well..

ive had good luck with a product called "freeze off" by CRC
can save some serious hassle sometimes,
if you can drill a small hole completely through the bolt do that first
freeze bolt, heat up area around bolt with torch of choice
freeze bolt again while everything is still hot
twist out bolt

same trick works with most any areosol, but a can of freeze off for 3 bucks goes a LLOONNG way, it also acts as a penetrating oil

first time i saw it was at an ACE hardware store, when i left there everything around the counter had ice on it ive found it at napa too

The hot and cold technique is used to fuse parts together as well.
