Brief Description: Enlarged holes of Counterbalance Brackets.
Have 3 more holes to enlarge to accept AN3 bolt. I went toHarbor Freight and bought a right angle air drill and a right right angle electric drill adapter, Neither would fit in the space between the CB Brackets and Hinge Brackets or the Ribs. I again used increasing sizes of tap drills attached to a right angle screw/wrench driver. Also tried step drills. The work was slow and hard, and my hand became sore. In the end, I was able to enlarge the holes to accept the AN3 bolts without tearing everything apart.
