FLM Rusty Assembly problems

Recently purchased the FLM Super ext chassis kit with the ext arms as well. Nice kit but have found a few problems. Missing e-clips, thing's not completely tapped all the way through, and problem's with mounting the shocks. First two I can deal with, third is a tad more difficult. The rear shock's themselves bolt just fine to the rear shock tower, but when trying to bolt to the rear a-arm there is a good 1/4 inch gap, if not more between the shock and the arm itself. I was thinking the goofy lookin alum spacer might be what's needed but when trying this route the included hardware doesn't reach the threads. Anyone else encountered anything like this?
