I have reconditioned an OEM Harada power antenna for my 1971 240Z including replacement of the mast and it is working properly. Now I need to find a replacement mount nut which has the conical shape and a rubber seal at the top to prevent a recurrence of the prior water damage. I have found a number of replacement antenna kits from Harada and Dorman from which I may source the nut. Does anyone already know of a good replacement before I begin a trial and error approach?
