OK,T-Rated is correct, Pin must be removed from at least one side. Need to drill out opposite side of assembly so that you can punch pin back out. Easy to drill through plastic assembly. Punch pin out, lift assembly off same side, lift the cross bar while at other side will release the other side-easy.
Only comment on Defender rack for the WK is that it is off center by about 1/2 inch due to mounting holes in rack. can't notice from sides, but is more recognizable from back where the "Defender" lable is not centered on vehicle.
Pics to come later--too dark now!
