I have a quick question? I have a 79 Chevy, SWB 2 wheel drive. I have put 2" drop shackles on it. Looking at the front leaf spring hangers, can they be flipped upside down? It seems that the two top bolts in the stock location would become the two bottom bolts (using the same holes) and you would just have to drill a couple new holes for the top bolts. I have seen the rivits removed and the hangers moved up and re bolted in giving a couple more inches of drop. Just looking at it and thinking? Am I not thinking correctly? Thanks for any help. Jason
