MGTF rear upper arm has spacers either side of the arm bearing. These usually corrode badly and if you are rebuilding the suspension it makes sense to swap out the old ones and fit this kit of stainless steel parts. It will be the last ones you need.
Kit comprises of long through bolt/nut, spacers for both sides a new stainless steel retaining plate and M6 retaining screws.
Sold as a pair
