when i had my accident and had my front end replaced, i found that i could get a set of tube fenders for half of what it was going to cost for two stock fenders and flares. of course when that happened, the idea of mass producing them was just taking off and everyone that was making them had them on backorder for 2 or 3 months, so i couldn't do it.
you only need one, so you might have to front some cash yourself, but this would be a great time to go flat/tube fender and only have to pay a few bucks.
I have a friend who is planning on going to tube fenders at some point before the end of the world, and he told me I could HAVE his fenders for a steal. Dunno if that will ever happen.
I am looking for a passenger fender too, and the wife won't let me spend $$ on flat fenders, though I may see what I can do about getting some TNT Custom ones that replace the OEM fenders. That just means I need to rewire side lights, which means I probably need to do the LED's in the grille, so it is more involved than just a fender swap.
there are lots of places to look at for your jeep fender. ebay or junk yards or online stores. there are also lots of choices to choose from, the budget you have would matter on what kind you want to install.
My friend just bought me a new Jeep fender when he accidentally crashed my Jeep in their backyard... It really looks great, i forgot though to ask him where he purchased it and if it is gently used... If you want new parts for your Jeep for free let your friends borrow your Jeep and before you know it you have a new one... LOL...
