I recently replaced the rear crossmember on my 1986 ex-mod 90 with one of these (LINK).
I finally got around to try and reattach the tow bar (Dixon bate style) and have run into some difficulties. With the lower support arms attached, the drop plate of the tow bar will not go back far enough and sits proud of the cross-member by a few centimetres.
As the crossmember came with chassis extensions, the tow bar brackets for the lower struts were already welded on so I know it is not the positioning of crossmember itself. I have measured (very roughly) from the furthest bolt hole to the back of the cross-member and it is approximately 34cm on the old cross-member (shown in the pic below), and 31cm on the new one.
So, I am now trying to work out where the issue is and how to resolve it. Based on the differences measured on the mounts I think I have narrowed it down to a few possible explanations.
As the tow bar was fitted by a previous owner it could well be the wrong one and the mounts welded in the wrong place on the old crossmember/chassis.
The mounts could be welded in the wrong place on the new crossmember.
Being ex-mod the mount locations are different, or the mounting locations changed at some point (other than the TD5 which from what I can tell is significantly different due to the fuel tank), and the mounts on the new crossmember are correct to the 'new' standard and I need a different towbar/strut arms.
Has anybody run into these issues before or know what could be causing the problem?
