when you put your cab on the frame to see the ride height, and you wanna make it lower, remember the suspension is gonna have more travel in the upwards direction so it may be a good idea to factor that in. some avies had struts, which would be easy to pull out and then move the suspension to its snubbers, but I'm not sure what year that started. anyway, just a heads up.
I put my 57 on an envoy xuv frame and suspension. I used the floor and firewall from the envoy. that made the mounts atc easy. it complicated lots of other stuff though.
keep posting pics, its gonna be great to see how you do this and what obstacles you overcome
