Had to jump in here because I'm I just finished replacing the driver's side outer front cab mount and part of that floor; not my first rodeo there and I expected to see a height difference but this thread sure helped me to understand HOW to get the cab level! That shackle setup (and adjustment) is a different setup than what I've worked with before. About to start on the passenger side, its much better but that outer mount is also failed (so the driver's side is understandably higher right now) - but knowing this I am able to do a way better job at making sure the cab is "sitting pretty" before I start burning the new metal in.
So Thanks!! [u][/u]
