I have the cap, now looking for clamps so I don't have to drill holes in anything. I am calling Leer & ARE dealers near me today. But I don't have high hopes that they will have them. Maybe someone on here has some they would be willing to sell?
All I can say is keep looking. I just found one after about 6 months. I was just looking local in Western NC. I am now looking for the clamps. If I cannot find any I will bolt it on. Good luck with your search. I also only looked on FaceBook Marketplace.
