Have the car on stands, which gives a little more room to work. Spent about two hours trying different set ups, with no luck budging the lower link bolt.
I did determine why the upper end came loose from the caliper carrier. Someone has been here before and the top bolt of the carrier end cap was loose, backed out about 1/8" (now that I know the cause, I can see the separation in the close up pic). I suspect it was loosened during a prior brake job as these two bolts hold down the brake line clamp. I don't think you have to worry BobK, just check those end cap bolts.
No more working tonight, it's dark and I'm frustrated.
