What was your final determination on this? I bought the same repop brackets from post #1 and I have a 2WD LWB with leaf springs and I have the same problem - I don't have a hole in the frame rail for the very front bolt hole in the brackets. My truck came with a step bumper and the front hole in the frame appears to be positioned correctly up and down on the rail, but needs to be about 2.5" forward. I am planning to use that same centerline to drill the hole, but wanted to find out where you ended up to make it work on yours. I would rather drill a couple holes than buy a new set of brackets.
