I have a 552nd series truck also .I installed a Mustang 2 front suspension from heidts. The cheapest way to do this is to buy the whole kit all at once. I am poor so I bought one piece at a time and ended up paying almost double for it in the long run. I think the mustang 2 front suspension looks like the cleanest install of all. I installed the disk brakes on the front. These are the bigger brakes from a chevelle. I like the stance it came out with. My buddy used an 81 chevy truck front end. This ended up being a big mess I think. He had to do a lot of fabbing to make the front sheet metal fit.
