Missing a piece for stream magnets

[discocarp]

I have been using stream rocks since I first got the 2x6100 streams, but decided to switch to magnets. I purchased 2 magnets for my 2 streams, but they're impossible to attach. I must be missing a piece that came with the original stream mounting hardware (which isn't needed with the rocks). I have no clue where this is. What do I need to order?

You need 6080.23 and 6080.40, they were in the parts kit that came with the pump, both pieces will run about $8 total.

Thanks! I sent an email off to PA about these parts and will order them asap.
