171-holding tank support and fender extension?

I took mine to the dealer who tightened the screws and closed up the gaps, but sheared one screw off in the process. After that, I still did not like the looks of it so I drilled through and  each bracket now has one stainless steel bolt with stainless steel washers and nylock nuts. If you drill, use a slow speed on the drill as a fast speed is an easy way to overheat the drill and then it gets dull and won't work. I went through several bits. Later I found some Cobalt bits at Home Depot that are much more durable. Even those will become dull eventually. I haven't yet found an effective way to sharpen them.

It isn't just the tank supports though that need work. The black and gray water drains also need better support. See my mods for my solution. I have had the black tank drain support fail twice, both times allowing the end to drag on the pavement. There won't be a third time!
