What is that BHJ supposed to fit? It's machined differently than the 2 for BBM w/ internal-balance that I have (a really one old and a new one I picked up a few years ago)... mine don't have round holes, they have oblong "slots". Can you tell if it's an SFI-approved or standard (non-approved) version?

At one point BHJ offered a rebuild service, which I used to freshen up my old one before putting it back in service; not sure if that's still an option. I also know they offer snout sleeves to use for reducing wear on their aluminum-hub models, but no reason why a sleeve can't be used for a steel one w/ the right interference fit. There's probably an OEM damper snout repair kit that uses a sleeve buried in a parts box somewhere in my stash, IIRC.

Not suggesting that any of this is cost effective, only that there may be options to keep it in service.
