Hi all, been an owner for 12 years but never really needed advice until now. I've just dropped the back axle out my 1.8 16V 1991 Corrado. A stupid question I'm sure, but does it have a rear ARB or has it been removed prior to me owning. Or is it simply the bar that runs in the crease of the beam? Pics on the net show a seperate bar fixed by straps around the beam. Assume these may be after market type?
