Help with early SME 3009 counter weight

Do you have a split (two section) counterweight?

All my 3009's (I, II non-improved and R) have had a rubber fitting inside the counter weight.

Perhaps the rubber piece has degraded and fused to the metal?

I used to see this part for sale on Ebay and @ A'Gon (dealer in Canada I think), but I do not see any listed @ the moment.

Anyway, my current II works fine with Ortofon and Grado's that are not too heavy and I'm using the the cut out/light weight Sure-SME headshell.

Thanks for the answers. I think I didn't describe well enough. On the arm that I have, the rear small counter weight is fixed at the very end of the arm and has no hole in it to allow it to move forward. The rider weight is hung from it. There is a center counter weight that does slide, but with it as far forward as it goes and with the rider weight as far forward as it can go it won't balance . I think I just made a mistake of inexperience in not realizing that this arm probable used a SPU head shell that is much heavier . At this point I think I will have to just chalk it up learning. Unless I thought maybe if I could find a rear counter weight that has a hole in it, like ones I have seen on later models, but that seems remote from what I 've seen so far. Thanks again.

I just found the arm currently for sale on ebay like the one I have. #290230983127
