Did a search - nothing forthcoming (or fifthcoming for that matter).

Will an A bar (bullbar) that fits a facelift TD4 fit a facelift V6?
i.e. the bumpers look the same, but are they?

Yes.Bumpers on facelift are identical, only different on the early non-facelift Freelanders

If you're buying second hand, make sure you get all the brackets. I think different bullbars may use different mounting points/brackets - but my one on my '99 has brackets that attach to the actual metal bumper and poke through holes in the plastic bumper to join the bullbar about 2/3rd way up - plus it also has 2 brackets at the bottom that feed through the 'valance' part of the plastic bumper and are secured by undertray bolts.

All these brackets need holes in the plastic bumper to be cut - so some dimensions on where these are might help you keep a bumper without visible holes afterwards!
