On Saturday Driffter33 and I modified my new Lil Skip's Gas tank skid to work with my heim jointed rear control arms (which if you've been following the build, increase my travel - a lot). My drive shaft was not just rubbing on the skid, but the 3rd member was getting hung up on it because my links allow the axle to move more off center and swing more forward then the rubber jointed stock arms allow. Lil Skip's makes a helluva skid plate and I want to make it clear that it is only because of my custom links that I needed to modify it.
1st we took a f*****g felt tip pen (sorry, movie reference)

and marked the area that obviously had to go and cut it off with the 'ol torch.
Then we mounted it up and checked clearance again with it flexed out and realized that if we weld the bracket to the skid in place then we can eliminate the bolt and gain more clearance. We also took a diagonal cut out of the vertical side to make room for the slip yoke.
^^ That bracket is just tacked on in this pic. Jay put a solid bead all the way around it. If the skid gets hung up on a rock, the bracket will bend before it will break that weld.
We put it back up and decided just to be safe that we should beat the tank in slightly to be sure the shaft didn't come in contact with the side of the actual gas tank. With the weight of the truck sitting on the bump stop, the driveshaft clears both the tank and the skid with no rubbing but it's close, damn close. What's the saying, "An inch is a mile"? In our case it about 3/16", haha.
Flexing is so easy when you have a forklift in the family.
Here it is in action completely stuffed and no issues.
In this pic it looks like the tank is exposed on that edge to damage from underneath, but it's just the pic. The skid still fully protects the whole underside of the tank.
Here are some pics of the run we had today in the snow

I tried all day to get myself good and stuck in 4Lo with the rear locked (which isn't easy) and I finally did. It's a nice thing to have one more button to push and just roll on out. Lockers rock.
