Got these made today at work. They are 1" thick and 1.25" diameter. I know body lifts are cheap but the material and labor were free so . My question is I've seen some of the kits with both ends flat and others with a chamfer at one end. Should I leave these flat or chamfer them? I'm aware I will have to move my fan shroud, possibly extend fuel filler neck, and possibly have trouble shifting into 4wd. Any other potential issues? I see some of the kits have a few small brackets that come with them, any idea what those may be for? Any thoughts, pointers, ideas, suggestions are appreciated.
