Some nipple-head at the Eagles Nest in Nashville, where they did some repairs in preparation for sale for the guy we bought it from, decided to replace only 5 of the 6 rear bags. I finally got around to pulling that last one (it was 61 wonderful degrees in Chicago today).

Our bus has no Norgrens. I will take a picture of the beautifully simple and inexpensive valves they used to use, before it goes back together.
I am also upgrading to maxis on the tag and replacing the drive maxis from the 30/36's to the 30/30's replacing all the 1/2in rubber brake hose to 3/8 with the 2 piece reusable ends, upgrading to gas shocks and replacing the drive tires with 11.22-5's. This will give me all the same very readily available and less expensive components that the trucking industry enjoys
The fat lady is tuning up.
I had the opportunity to scarf up a set of the elusive Mae West bags (the0126's) That same shop replaced 1 of the two up front and the L and R sides are different. They are going on the steer and I plan on pulling the brake drum to see if I can find that thunking sound down there in harder shorter stops. I remember a couple other folks mention that same thunk up there, hopefully I can definitively resolve that.
