Looking for S70 load spreader

Hello mates,
I’m looking for replacing my load spreader on my Superstringer S70. Unfortunately, I haven’t found a compatible model neither on tennisman.de or aliexpress…
For information, the load spreader looks like a plastic “trident” (I think it’s quite unique; even the S90 does not share the same model).

Before going ghetto with DIY solution, if any BC member has any idea where to find it… Many thanks in advance!
