How much lift is the coil conversion? It looks like about 4" over stock but pictures never tell the whole story, how old it is, etc.
SOA 8.8 vs. SUA D35 is a good 6-7" taller because the 8.8 axle tube is thicker and the SOA mounts (i.e. the "antiwrap" ones) are sometimes quite a bit taller than the stockers too. I think a waggy spring is 1-2" taller than a YJ spring as well so its probably gonna be a little taller back there, maybe 2-3" or so from the looks of things.
The axle wrap sucks with SOA unless you add an anti-wrap bar. You will break stuff without one if you are hard on it. Lotta pinion motion just doing basic accelerating and braking on the street without one.
