So I finally got time to work on installing the rear 2012 springs.
The rivets holding on the front spring hangers were the worst I have ever removed. Cutting the heads off was easy, but i broke my air chisel trying to punch out the rest.
Ended up drilling partially through the rivets and then punching them out with a 4 lb hammer and a punch.
Just mocked up the hangers using the 2 forward bolts in the rear holes of the hanger. Got the springs installed and the axle bolted in. Noticed that the front bolt for the 12 springs is larger than the hole in the front spring mount. Going to have to drill that out, so I just used the 02 bolt for now to get it all mocked up. Going to try it with no rear block to start, but won't know final setup till I get the body dropped down on the frame and see where everything sits.
Working on the rear shock axle mount now. Ended up ordering a second 06 driver side axle mount that I plan to mount on the passenger side to get the orientation I need for the Excursion rear shocks. The original passenger mount for the 06 axle aligned the shock to the front of the axle. The Excursion has to have both shocks in the rear of the axle as they attach to one of the frame cross members. The 02 shock mount wouldn't clear the rear sway bar that I added to the rear axle.
Once I get the orientation I need, I will probably end up welding the mount to the axle tube as it will not line up with the tab that normally keeps the mount from spinning on the axle tube.
Then I will make a template and drill the holes to mount the front spring hanger. Also want to install the air bags that I have to make sure everything bolts up and the rear suspension should be about done.
