Thanks for the quick reply. I just finished that beer and am going out to have another crack at it. Yes I did try tapping it in to get it moving but I think it is already bottomed out. I don't think I can get the head off without taking the rail out. unless maybe I break the chain. It is less than 2 degrees stretch though and I didn't borrow the chain tool. I'm going to try to sneak a real dent puller past the condensor and go for it. I bet the bolt snaps.
