So here's the issues:
-
Studs are 24" apart so I can't mount to 2 studs, but I can mount to one.
-
There's a 3/4" gap between the drywall and the concrete block so I can't use toggle bolts.
The mounting bracket came with 2.25" plastic drywall anchors for the lag bolts, but I believe they're meant to be used directly against the concrete and I'm afraid the gap between the drywall and concrete wont allow for enough penetration of the anchor to support the TV. There would only be 3/4" of the anchor in the concrete.
My plan was to have six points of contact, 2 in the stud in the middle and 4 using the concrete anchors on the corners of the mount but I'm just not sure if that'd be enough to support it.
Any advice would be appreciated!
