any difference between 3/4 and 1/2 ton?

8 lug vs 6 lug wheels and the frame is thicker gauge material and a little deeper. Click the link in my signature, scroll to the bottom of the page that pops up and go the year index. Pick your year and look a the index. There is a table that gives the differences. Unless its a 9' bed wheel base is the same for 1/2 and 3/4. Then have the same spring mounts. Lots of build threads to look at to get a idea how low you can go with stock suspension mods, then clips and c notching the frame to get lower.
