OK, My dads friend a mobile welder, cut off a hitch lock for someone off of a semi trailer, the guy gave the greasy b@$t@** to me. Looking at it, It had a recessed paclock 100ic in it. First things first was a good wash with wd40. Put a short hook in and 15 seconds later, I hit the control line

, After thumping the paclock for a wile the core dropped out but the lock was still locked into the assembly, but i cant figure out the mechanism that opens it. I need help with figuring the 2 pins that are right in the body, that unlock it.
