2nd gen Xterra/Frontier guys with spacer lifts on the front getting coil bucket contact. Tried a different kind of bumpstop similar in shape to the ones Readylift includes in their kits. Need to enlarge the bottom hole on the UCA and dremel off 2 small corners of the bumpstop but it will fit. Bolt comes up through the top hole on the UCA so it easily bolts on. Zero CBC with bumpstops from early 80's GM cars.
