Some of the vendors have the arms and heads but the arms are probably too short for the big bolts. I thought about the same thing for my truck, I figured I could get two new arms and lengthen them. I ended up with west coast mirrors from Craigslist for $20 and the truck had already been modified with west coast mirrors, I didn't have to drill any new holes, for now I'm happy with it.
