Thanks Nick,

I presume that the stresses must come from the chassis flex then as the three points of contact are crosshead both sides of the rad and the cross bar between the inner wings or valences as Morgan like to call them. Perhaps a modified top mount might help, I'll have to get my thinking cap on! First though I think is to ascertain what force direction is causing the issue. When I get a chance I will have an investigative look! and report back. Odd though when you think that a plastic and alloy original can last reasonably well yet the forces applied can rip off an aluminium welded bracket from what must be a much stronger item of equipment!
