Thought I would share this with others who may have had some trouble getting body mount bolts out without twisting them off. Some of you probably have already used this method but some may not. It sure would be quicker with the old trusty smoke wrench.
Using a 3/32 drill bit pressed into the end of a mandrel 5/16" dia. x 6" long essentially making a long drill bit but not as easily broken. I drill one hole thru the threaded joint at a slight angle and what you have is essentially a tap turning inside a die, there is only three threads to drill thru since there is a huge champfer on ea side of the nut. You will find they do not require as much torque to break them loose and once they are every bit of movement is cutting RUST from both the nut and the bolt. The positions you have to work in to drill the holes makes one say things they shouldn't but did both 67's this way. Takes about 10 minutes or less to drill ea. hole but GOD only knows how long it takes to get ready.
Now if I can get the picture attached you can see.
