Thought I would post up some pic's of my install on Korbin's '82 C-10. We raised the crossmember up into the frame 1.5" and also used Porterbuilt's new Forward Arms (Lowers only at this point). Here are some pictures from this past weekend:
I still need to do the support bearing, but I am waiting on Rob to post up some pictures of the correct set up for a '73-'87 frame rail. I have a PS pump, hoses, and cooler from a 2000 GMC that we are going to use in the final installation. Enjoy!
