Thanks! yes, both upper u-bolt plates and I'll have a d side lower option too (we're still finalizing the design, it's quite complicated) The frame bracket uses the 2 lower steering box bolts (longer bolts will be provided) as well as the rivet hole between the coil bucket & engine x-member. The spacer is for this bolt. If you run the dual shock kit, this rivet has to come out anyway. If single shocks are kept with the stock coil bucket you just blast out that rivet to mount the trac bar bracket. The u-bolt plates will take single or dual shocks.
