I just bought a house and the person for me mounted his TV above the brick fireplace. I would like to do the same, the only problem is I can't find a mount that fits the existing bolt placement. Every mount I've found has the corners but no option for center placement. The current setup has a series of three bolts drilled into the brick at 8 inches apart in a horizontal line. Has anyone seen a mount like this and if so, can you recommend a mount?
