My first set of rear air bags.....did I do okay?

[prostreetC-10]

I know NOTHING about air ride suspension, but after seening a guy in my town with them just on the rear, I wanted to do that to my truck. In a another year or so I will finally convert to disc brakes and want to go with a drop spindle. My truck needs another 2" off the front and back. I already have 6" drop springs in the rear and wanted to go with air bags for that extra amount. The frame is notched.

I was at a garage sale on Friday and a guy was selling a really nice set of Firestone overload air bags with brackets and lines. I did a good inspection and no rub marks or anything on them. I realize I will have to fab up my own mounting brackets which is cake but is there any reason why these bags won't work?? Oh yeah.......I paid $10 for both!!!!
