Can you change the shock shims/valving for increased stiffness because of that shock angle? What angle were they from the factory?
The angle increases during compression, which will reduce the shock effectiveness at full bump, works, but not ideal. This can be fixed by firming the compression and rebound. However, since the shock angle changes with the travel arc the rebound will increase and decrease inversely proportional to the angle. It will be the stiffest when straight up and the softest when angled. They are many ways around this with internal and external bypass, etc. Just making you are aware of how it will work. I went through the same thing, albiet with not as nice of leaf springs as you, and I wish I would of just went with links in the back too. By the time you fabricate a traction bar to prevent spring wrap you can build links.
Its looking really trick Ben, I like the fab.
