OK so my wife and I just moved into a new rental and it has a mount bolted to the wall. We want to hang our TV on it but apparently the previous tenant took the bar that mounts to your TV with them. I called bestbuy and they said you can't buy just the bar but have to buy the entire kit. I have a 52 inch LG plasma TV and would appreciate some help figuring out if I can get just the bar or if I have any alternatives. Thanks in advance for the help.
