I need a keel roller
 

I need a keel roller to keep the keel from hitting the forward most ALUMINUM cross member of my trailer. I have only been able to find galvanized brackets which shouldn't come in contact with the aluminum. Does anyone know if I can buy an aluminum bracket or if not what to use between the two materials? Or would a keel pad work? I put a similiar post in the tech section last night and have not gotten a response. I am counting on the Boyz for info and I know some of you are browsing this section now.
