Hey sorry man, I forgot you asked for my drawing. I can't find it on my pc at work. I will have to check to see if I have it at home. I used 1/2" 6061. Basically all I did was remove the stock bracket and use it as a template for the thicker one. Radiused the edges and bolt it on. You will need some longer screws, I used Stainless Steel Button Head Cap Screws.
