Found time to make a little more progress...
Completed the air management rack for the tanks, manifold and compressors. I'm happy with the end result - clean, functional and compact.
View from underneath (hard to get a good pic)
With all of the components mounted.
Needed some extra room so I removed a portion of the floor cross member. Drilled out the spot welds (WHAT A PAIN) and cut the rest with a cut off wheel. (I accidentally deleted the last pic of the piece completely removed but you get the idea
The air lines along the frame rails are installed- still need to connect to the tanks.
Currently I'm determining where to mount the height sensors. Looks like this is the best approach for the front. Still need to fab a mounting bracket and secure it to the A-arms. The A-arms are cast and I don't have a brazing torch so bolts will be used to secure the bracket to the A-arm.
Amount of sensor arm travel.
