Where to find rubber tip for Pearl BLX BD spur

[sonot]

Hi there!
I bought Pearl BLX-83 vintage kit a few years ago. Bass drum spurs are missing rubber tips and now when I'm planning to sell the kit it would be nice to find those from somewhere. I bought already RHS-1R/2 set (For bass drum feet SP-20 (EX, ELX and EXR)) but those won't fit.
Any ideas where I could find right spare part? Preferably from Europe as I live in Finland. If genuine Pearl tips aren't available anymore any tip that fit would do just fine. Thanks in advance!

Not sure if this is it. R-30 A. This is Pearl
located in the Netherlands.

In '87 the MX, MLX & BLX had the 730P bass drum spur. In the parts catalogue the rubber tip did not have it's own code.
