1982 Swingarm

I have the swingarm off my 1982 LTD 1000 for powdercoating.I've ordered replacement bearings am wondering if I should drill and tap it for a grease fitting as it dosen't have one and I assume the thinking was the bearings never needed greasing? I have manual that covers 1973 thru 1980 and it has greasing the swing arm as part of regular maintenance but know when they stopped recommending it.

Couldnt hurt
