I used stake pockets off of my parts trucks to make them. Then used 16 gauge 1-3/4" tubing to do the top. I plugged the ends with frost plugs 1-5/8". My end plan is to fabricate some "fender extensions" and bolt the stock fenders to them. A custom dually fender that can be returned to a single rear wheel if wanted. I think that will turn some heads! Thanks for the comments guys!
