May I suggest you drill a small hole (the size of the spray nozzle extension tube that comes taped to the side of the can....) directly through the frame rail where the threaded portion of the K member bolt will poke through the rail at all 4 locations. Now spray a LIBERAL amount of your favorite rust penatrant and let it soak overnight. If your K member has been in the car from day 1 you *might* have some corrosion issues. Strip one of those bolt holes and you'll be pissed beyond pissed.After everything comes apart, weld up the holes you drilled or at least seal it off.
I like that suggestion and if those bolts are stubborn I'll do that. So far everything came apart very easily, just hand tools. Got one torsion bar out by hanging a pipe wrench on a little crooked and giving it a few good hits, after I took my knife to the back side of the mount and cleaned around where the clip was. The other side I didn't try too hard, I figured I ask the question before I broke something. I saw the tool in my service manual, and now that I know they are available, I'll try to get one. The right tool always seems to make the job just that much easier.
