Well I finally got the kit installed. I ended up taking a grinder to a 9/16 open end wrench and taking the thickness down to 3/16 and then removing material from the sides till I was able to get the wrench to fit into the small opening. I did use my own air line and fittings (Parker brand) and not the ones included with the kit. It's been aired up to 20lbs for about an hour now and no leaks. I drove around with 10lbs in the bags with no load on the truck and it drove fantastic. I think it handles bumps and potholes better than it did when stock. The biggest problem I had with the install was a lack of any photos. Here and on the web site all show the old style set up and not the new one that I received. I'm including a pass anger and driver side installed photo here for anyone in the future that my need it. The bags do slightly rub against the coils on both sides.
And John if you look at the pics and I installed anything wrong please let me know...
