When I took out the stock air box bottom I replaced it with a flat piece of Lexan (anything would work), for the 6637 to rest on. This prevents the fender lining from getting beat up over time. As my white truck doesn't have a a bracket to hold the filter, it just rests on the Lexan. Lexan is attached to stock holes of the original air filter box, so far work good.

I have the real Tymar with the muffler clamp so I used 2 all thread bolts, 8 nylock nuts and 4 large fender washers on both sides of the fender liner. No damage yet.
