Bob,
The brakes work great with that booster! One of the best upgrades. I also have cross drilled drums all around. I bought them from Brotherstrucks.com. Not sure if they still sell em. I routed and bent my own lines as the layout is a little different on the NAPCO's. I just went down to NAPA for everything. It was a bit difficult, and I had to do some loops here and there so I didn't have to cut the lines. If you have a good flare tool, you won't have this problem.
Nice photos, I remember when I was at your stage. Are you using the 7 leaf front NAPCO springs? I still have the 6 leaf springs and when I'm out wheeling I hit the bump stop quite a bit. I plan on adding the correct 7 leaf springs in the future. I just hope I can still get the truck in the garage as it currently clears by only 1/2 an inch!
Let me know if you have more questions.
Michael
