Been slow moving, kids do that apparently. got the new crossmember fully in with air bags finally. had a hard time with getting correct A arm and making sure i was tightening the shaft nuts correctly essentially just turned until they bottomed out and I am supposed to torque to 200+ but i cant even get that. anywho.
I ended up using the newer mounts because they are stronger. I added some material on the back side instead of drilling bigger holes on the frame. Either way works at this point id say.
the air bag plates were misaligned with the LCA I thought so i shifted over a hole and made the pipe fitting a larger opening.
I also installed a Transgo hd2 kit in the 4l80. I am waiting for my single disk CIRCLE D TC to show up in the next few days. Here is a link to my process
