to make a long story short...
driverside-front engine mount (a/c compressor attaches to this)
needs to be replaced but the problem is that when it was installed one of the bolts that threads into the frame of the car was forced to hard and ended up breaking the weld of the nut it connects to in the frame

i need to get this out...thinking of cutting into the frame from the top in order to get at the nut with socket/wrenches whatever works and then back off the bolt...then re-weld the nut back onto the frame from the top...

any suggestions!?!?

anybody actually understand the nonsense i'm giving you?
