Upper Control Arm bolt

YIKES! Well, someone here probably has a control arm & bolt assemblies for you, if you have to go that route. The car doesn't look rusty. I guess water worked its way in there. Could have been a worse, way more costly problem too, just remember that before you start cursin'. :lol:
Luckily, I purchased a pair of arms some time ago and had the bushings and ball joint installed.. Same with lower. I figured that way it would be an easy in and out job with no down time getting joints and bushings installed.. As usual, my "easy" quick job turned into a PITA...lol
