do i need bushings for my cutting attachment on stihl hl?

i went to my local sthil dealer and told him what i thought i needed. when we looked up the spare parts diagram i saw right away what i was looking for. the spares are called needle bearings costing £3.71 each +VAT. the old ones had worn away completely and when i fitted the new ones the hedge trimmers are now working perfectly again.
