Help me with a Fidelity Research FR64 part

I typed the word “BY” when I meant of course of Buy, in my post above. Most likely this happened because I am speaking into the phone, rather than trying to type with my big fat fingers.

Dover, I certainly could be wrong, but I think the OP is looking for the large nut that goes under the tonearm mounting board and mates to the thread at the end of the vertical shaft of the FR 64. In any case, at least for my FR 64S, the counterweights are not threaded at all. I guess I am making another assumption that a stabilizer is a counterweight.

I will repeat that i have the original part, ask if you need it. Mine has been replaced with N-60 nut on one tonearm and with B-60 base on another.

That's a very kind offer from Chakster.

Look no further OP.
Not a surprise Chak has one.
Seems to have collected a huge amount of analog stuff on his journey.
I would take him up on his kind offer.
