Thanks, John. I went out of got some PB Blaster. I also dropped Jason from OTT a note to see if had any tips.
In case anyone comes to this tread having the same issue as I did, I wanted to add Jason's comments for information. Im not sure which tip worked more (John or Jason) but eventually one helped to loosen it. Thought it was still very difficult (it took two hours to do the two back jacks!!)
Anyway, Jason said that some of the guys use Red Loctite when closing those Allen screws. So the only thing that will loosen the loctite is heat. He said put a flame around it for a short time. I did that, I also heated the allen key and left it in the screw to help things along.
But I got there eventually by using both the PB Blaster and the flame.
Thanks again to Jason and John!
