Pete,

While I found it a simple DIY, I've also spent my whole life working on vehicles. Most guards hook up with a short length of chain and a bolt through the frame to attach the chain. A hole may or may not be present so be prepared to drill a hole. It should be noted that a rear guard does help, but does not eliminate the toad from being a mess. The large radiator fan sends a significant amount of dust and dirt back onto the toad.

Okay, you have both given me the confidence to undertake this project on my own.  Most case scenario, I send it to the mechanic to fi my install.   

I was concerned when they told me I needed some form of rebar and extra parts etc to install on my Fleetwood Pace Arrow.  Parts guy also mentioned  two different flap lengths and that I was supposed to measure from the ground to the frame before purchasing the correct one.  

You guys are super.  Thanks again for the encouragement and insights.
