Todd,
If concermed you could always glue them to the pole.
Layer of glss around the pole to insulate the stainless from carbon. Bed them into glue and then wrap a couple layers of glass around the stainless tags on the cheek blocks.
If concerned about appearance you can colour the glue black with a picgment in the resin when mixing up the glue and we can now buy epoxy resin with a hardenner that does not discolour due to UV. So the glass can remain transparent.

So if concerned, with a bit of care and planning, you can probably make the attachment almost invisable.

Regards,
Phill
