La-Z-Link It's a post I did a while back on it. Home Depot didn't have my screws. Went to 6 Home Depots and didn't have more than 2 on hand. Went to Lowes, had them in special screw & bolt section. Get the black hex screw ones that are metric. They are higher tensile strenght. I took one screw out and just lines the screws up next to one another to be sure. But the fit like a dream. Use loctite up on install and search on how to install correctly. Good luck.
