easy...3 x self-tappers thru the factory flares and one 11mm bolt & nut thru the factory plastic splash shield.
"Jeep" wording faces backwards
8mm heads x 20 or 25mm 8g with washers, and I think the bolt is a special item but could either be replicated with a hollow spacer or screwed flat, like on my Limited
they do a fair job, I often have to traverse a muddy bit, and afterwards, just road speed off the tyres will throw up a fuck ton of dirt
all copper-slipped and fish-oiled now
