Yep, this is Don with Bro-Flaps. They mount to the existing fender-liner holes like you described. If you decide to retrofit your RokBlokz to mount to the front like ours mount, message me and I’ll send you some blems laying around the shop . You’d also need six u-nuts and six buttonheads with washers.

Haha, tell your son he’s now the Professor over “product evaluation”:). I think I found you in the system. Address in Martinsville, right?
I'll let him know. Yes, we are!

@BroncoStang Do you mean the bumper cap on the rear of the steel bumper?
This plastic block that's behind the liner, the clearance kit strips it out and I think the liner uses a couple mounting holes in it; but JKS includes replacement brackets so I guess it would still work? Idk, might just be over thinking this.

I bought some of your blems a while back and they are perfect for 37’s. I cut an inch off the rock rails and they hug right up against them. Very simple installation.

Im loving the cooperation and inspiration we have here!
I just initiated the final steps yesterday and she is on 37s now!
Caveat to this is minimal lift and mods....

Added a 1 inch front space and a 1/2 spacer to the rear using level kits to get the lil bump up. Have a 1/2 inch rake in the rear for gear and trailer. It took 3 separate level kits Frankensteined to make it happen. Not all spacers are the same thickness which is so important. The wheels are 17x9 with a +12 Rocktrix 114. Tire are the Blackhawk Ridgecrawler RT. They were shy of 300$, and are not stupid heavy.

Took her out on some hills and ditches to flex and ONLY had slight rub when full force turn on fully compressed....nothing with swaybar or normal turns. Still drives and rides as before with a lil extra humm of RT that is really a MT. They measured at 36 3/8. They are quite rounded on the tread so some squish for tread patch.

The Broflaps are perfect! No need for any rear well mods.

Now all is left is the SC flashcal+ to change tire ratio and low pressure warnings due to 37s need less psi.
Plan on an 87 tune as well.

Just take a sawzall and cut that corner off.

Almost went that route. But I'm currently unable to weld them myself and don't have anyone I trust. Decided to stick with the stock mounts. Only cost me a couple Diablo blades anyways so I'm happy.

I banged into that on a hard left turn in sand. Had to zip tie the fender liner to the bottom tab but I have DV8 fender liners coming to replace them.

I'm not saying that's going to fail, but I wouldn't trust it.

There's literally no reason it would ever fail. It has more structure than most body mounts ever have. My view is I trust this over having somebody weld a new one onto my frame. That has more question marks for me than this.

Yeah I deleted all that crap yesterday and rerouted the wiring harness including the plugs up in the fender.

I have those stinky fab body mounts. Haven’t had time to do it yet, and I agree, you don’t want just any yahoo welding on your frame.
I weld for a living thus my laziness to get them installed lol. What’s the saying ? A roofer’s roof leaks?

Started hacking away tonight, so far working pretty well. Will grind it down and clean it up then do passenger side later this week. My JKS kit arrives on Tuesday as well but I don't think I'm gonna use it.

Nice! Looks great!
You might could use the rear brackets, and sell the front mounts to someone else on here.
