Heck, for the other end (the one that bolts to the body mount) I just went to the dealer and bought 2 new mounting brackets, 2 bolts and nuts and just replaced the stupid thing when I installed my GMPP rear arms. I got the knuckle bolt out ok, but the drivers front mount was not moving at all. Instead of beating/heating/cursing at it for hours on end, just said f it and replaced the assembly. Well worth the $$. IIRC the 2 mounts and hardware were no more than $40~ or so.
