WTB: Shimano UN-55 driveside endcap

[CMR]

Hi all, I think I may have accidentally donated the end to my bottom bracket to the local co-op and can't find it!

Looking for the driveside endcap piece for a Shimano 68mm UN-55 square taper bottom bracket. Just the plastic/aluminum piece shown on the left of the pic in this linked page:

Bought from Riv, so counts as Riv content right? Ideally someone has one laying around for cheap/free from a worn out bottom bracket, and I can pay for postage.

Thanks all!

If no offers present themselves look for one of these:

I had to pick one up once to replace a cracked plastic cup.

FWIW, the Problem Solvers up-cup for the UN-54 is too small of diameter for the UN-55. I have all of them and tried it out of curiosity.  If you shop around online you can find UN-55's for less than $20, if you go that route.

Good tip, Garth, thanks for clarifying and I therefore retract my recommendation for use with UN55. Come to think of it, I have no idea what model I specifically used it with as it was a few years back and still installed but must have been a UN54 or below as it definitely replaced a plastic cup that cracked. I do now recall doing some fine sanding of the the interior circumference of the cup, come to think of it. Was in fact a little tight on the bb I had, but not by much. I’ll have to see what model I have it on.
