I took four pictures tonight for anyone wanting to see them... Trucks pictured are a 2009 F350, and 1994 F350... Both trucks used bag kit Firestone 2550 and B&W hitch 1108... I'll put a small description above each picture explaining what you are looking at.
Picture #1 . This is the 2009 truck showing the stock unmodified top bracket and spacer from firestone

Picture #2. This is the 1994 Truck showing the extended top brackets 2.5"... They only need to be lengthened on the straight section, but I kinda over engineered them overlapping new steel, grinding the welds and painting them.... The spacer you see that looks like a piece of pipe with threads on it is indeed black iron pipe 1.25" long... My kit came from ebay and was missing the smooth round spacers provided by Firestone so I used what I had laying around.... The 2009 has the same spacers, you just cant see them from the angle I took the picture and the lip on the frame is hanging down.... But behind that I assure you is the same 1.25" spacer

In conclusion, everything fits well with no rubbing..... There's not alot holding the bags on, but I assure you they are sturdy and unbreakable.... I've ran 100 pounds of air pressure in these bags on carrying 23,000-24,000 pounds on a gooseneck trailer with zero problems... I've also sled pulled for years with this setup on the 2009.... If that didn't break them nothing should
