I've just fitted a DIXON-BATE adjustable towbar to my '06 90 and everything went on fine except for one thing...the two arms that bolt to the underside of the chassis (using the lashing eye bolts) do not sit flat on the chassis (and strengthening plates supplied with the towbar). There is a gap of about 3mm at the rear end of the mounting plate on both sides and although the bolts torqued up OK you can see the bolt shaft if you look into the gap. Is this OK...I cannot see a way round it and I have checked to make sure it's assembled correctly. The supplier gave me a 202046 (Defender 90,1999 model) and have assured me that it is the right version for my vehicle.
