Lost fin screw for foamie

Hi guys - I recently bought a second hand foam surfboard (mainly for when I’m struggling and need a confidence boost!)
It’s a decent board - very solid with reinforced foam round the edge so should last me a while. Only annoying thing is that one of the plastic fin screws is missing
. I’ve been trying to look online for one but the only thing I can find is a package which includes the fins as well.
They’re such cheap looking things but it looks like I have to pay a fair bit to get a spare. I wondered if anyone could suggest where I could get hold of one or, better still, whether some kind person out there may have a broken foamie with a spare screw available?!
If you can help that’d be awesome. No worries if not though
Thanks
Joss
