In a posting below there seems to be a few guys who wanted a "Lip Lock/grip". There is a store down in Virginia called "Green Top". They are having there spring sale until April 6. Great prices! I know they have the Lok's on sale but I don't remember which manufactures. Phone is (804) 550-2188.
I don't know if they have a web site or not. By the way, I am not affiliated in any way with them. Good luck.
