Crash bar armature easy to remove: 2 lower bolts two upper nuts each side. Also helps if you free headlights to enable access to upper nuts.
Whilst doing this. Had a moment of inspiration (I think). It would save a lot of time if the longitudinal member has an inspection cut into it near to the nut on the upper arm shaft. I do not think the member is structual (but could be wrong). The access opening could be close with a steel plate.
If this was posiible would save removing bumper etc. Naturally too late for me now!
