Looking for wool pads for giant tempo spinning bike

Hi,
I've got a Giant Tempo spinning bike I bought 10-15 years ago. Local dealer no longer carries Giant and I haven't found these pads online anywhere. Any suggestions where to look? Is there somewhere I can buy the woolen felt and replace it in the existing holder?

Thanks for any suggestions!

 

All the searches came back as discontinued item and I found no one with them in stock. I might be time to hit the local hobby shop / craft store and but some wool felt and make your linings to fit you backing block/pad holder.

Giant P/N 12004 if I've got the correct part.
