Ok, I did a search and still didn't find quite the information I was looking for. I'm thinking about upgrading to 1-ton axles. What I need to know is what trucks I should be looking at that would be a direct bolt-in. My fabrication skills are kinda limited. Any help you guys could be would be greatly appreciated. Oh, my project is a 1978 Blazer with 400sb and 35" tires.
