I would like to thank everyone for the answers you provided. I asked a gentlemen I worked with, and he said it was the spring perch. Evidentally its two pieces formed together and the factory ones arent welded solid, just stitched. Again, thank you for all your help. I have a long way to go on this project and I'm sure I will have alot more questions, so please bear with me. It seems like the little details are whats killing me. Any tricks of the trade on that year truck would be helpful.
