I ran into an older mechanic I used to sell parts too years ago--I asked him if he had and tricks regarding getting these busted lock pin bolts out,he was "the guy" who always came up with simple solutions to common auto problems..
He said he tried many methods,the ones listed here previously,like a pick,drilling them out,etc...the way he had success most often was a method he tried once with success..
He used an arc welder and a thin electrode like 3/32" and about 70 amps,inserted the rod into the bolt hole,careful not to let it touch the sides of the bolt hole , and let the rod melt into the remnant of the bolt,then shut off the welder and let it cool for several minutes,to allow the rod to "weld" to the broken part and also let the carrier absorb the heat..
If you were lucky,the rod didn't weld itself to the bolt hole,and you were able to grab the rod with vise grips or just bend it at a 90 degree angle and unscrew the remains of the bolt..he said it worked pretty well,usually there was enough oil in the bolt hole not to let the rod weld itself to it,but letting the rod melt against the bolt remains burnt away enough oil to let it penetrate and hold..
He also added "those bolts are a friggin ass ache--why they couldn't come up with a better way to retain the cross pin,I dont know--like drilling the hole all the way thru and use a nut & bolt...
