Mike, looks like you did a nice job, but I couldn't help but notice the shackle angles. I did mine last year and I read somewhere that the angle of the shackle in relation to the leaf was critical to the leaf functioning correctly. I had to reposition the upper bolt on the shackle foward to get a workable angle. This tech article covers it.

Yeah, I know the angle is wrong... How did you "reposition the uppper bolt"?
