Ryan, bin the mk1 out bound rear ARB and switch the to the mk2 inbound ARB and can easily fit a 24v granny rear or escort cossie 22mm ARB wouldnt need the mounts at the side then! what happened? look like someone has pulled the captive nut through!! on mk1's i've worked on they often shear there! one again you can gain access to the inside of the box section from above get a hole cutter and a nice grommet to cover it up later
