Rear mud flap replacement

Is whatever Winnebago used to attach the flap, still in place? If it is, this is easy. What I did, was go to Truckstops America and I bought an 18-Wheeler/Trailer Mud Flap. I chose T/A's because their flaps had all square corners, nothing rounded off. 36 high by 24 wide. Then I cut it in exactly half, giving me two new 18x24 flaps. A utility knife, against a straight edge, will cut this material. I was lucky to have a 1/4" leather/gasket punch and made the holes I needed with it.

On ours, the flap AND bracket were missing on one side. I made a new bracket out of punched angle steel available at Home Depot. This steel is probably out 18-gauge. You don't need the heavy punched angle used for shelving, hanging A/C units, etc. The stuff I bought "can" be cut with a good tin snips.

If you need a pic, I'll snap one and get it posted.

I used a front door floor mat cut to size.

Both of my mudflaps are missing but the brackets are still there with the bolts. If yours look anything lie mine and the bracket is still good get a three foot piece of 1"X3/3X1/8" piece of weldable steep from big box home stores. Drill mounting holes in line with bracket holes, one piece clearance and one side tapping size, sandwich all four pieces together. 5/16" - 18 cap screws should work fine.
