I am hanging a TV in my condo. The condo was built in 1967. The wallboard is very thick, around 3/4" with less then 2 inches behind the wallboard. I was going to use GripIt anchors but they only go up to 5/8" I then tried Hilti HTB-2 Hollow wall metal anchors but the toggle is to long to make it all the way into the hole so that it can spring out.

I am wondering if I take the two lag bolts that came with the mount and screw them through the drywall and metal studs if that would hold.

The TV is 40 pounds but the mount can extend 18" so I am worried about torque.

Anyone have any suggestions of a anchor I can use?
