did mine today.
couple of notes:
1) would have taken a LOT less than 8 hours, had the bolts not been so rusted into the mounts. We tried buying one of the chain vice grips - didn't work worth a damn. couldn't get them to grip the mounts. after fighting with the mounts for several hours, we started hitting the mounts & bolts with a torch - just a regular propane torch. not enough to melt the rubber mounts, but the heat either melted the threadlock that Ford used, or caused the metal to warp enough to make it really easy to get the bolts out.
2) mixing & matching the bolts is a pain - the shortest bolts go in the back. the bolts inside the b and c pillar (rear passenger floor board)require a couple extra washers under the bolt head to snug up.
3) the front bumper mounts didn't work out for me - we found it easiest to cut them in half and remove ~1" of metal from the middle.... this moved the bumper up 3" as required, and it was STRAIGHT up. the bumper cover hides it all, and since it's snug, it doesn't move.
4)the soft rubber part of the front wheel wells needs some trimming to not get caught up in the suspension. It may also help to punch a hole or two on the ridgid plastic and either relocate the push in fastners that hold it together, or add a few (the rear half of the front wheelwell)
5) We had access to a lift. this made the steering extension REAL easy.
keep a few things in mind:
*the steering shaft that gets extended is a telescoping rod - after unbolting it from the firewall, just collapse it to move it out of the way to work on it.
*we ground the inside of the extension to fit over the part coming out of the firewall AND the part that fits inside the telescoping rod.
*the steering rod is KEYED - it only fits one way - be careful that it all goes back together the way it came apart, otherwise the wheel won't be straight when your truck is driving straight.
6) the body mount that is aligned with the B pillar is a BEAR to work on.... those vicegrips wouldn't allow us to get the vice grip chain around it.
7) when heating the mounts with the torch on the crivers side WATCH OUT FOR THE BRAKE LINES.
8) we flipped the back bumper (I have a class IV hitch) - i'll take pics of anythin i do to get the bumper cover back on - if it works.
