Bongo Fury

As a non technical 1997 Bongo owner, I would be grateful for advise following recent MOT - Advisory info showed that both sides of rear anti-roll bar had 'slight play in a pin/brush'. Should this be done soon as I will be driving around festival muddy fields with a fairly heavy load over the summer? If so what parts are needed and how much is it likely to cost at my local garage to have the work done? Thanks!

get them to do the lot

2x ubrackets ...2 bolts each

2x rubber bushes held be the above

2x drop links 2 bolts each

should not take 45 minutes

main problems getting them undone,shearing them off

would help to spray with wd 40 some days before going to garage

Thanks - great help!
