If you are looking for a replacement for the on-one crank i bought this: https://it.aliexpress.com/item/32700975019.html?spm=a2g0s.9042311.0.0.27424c4d8vfSo0 it's a different size from the shimano ones and i straggled a bit to find the right replacement

Good luck. I recall now the old pomps did come standard with an on one external track crank - they don't exist anymore, but you could ping planet x an email to see if they remember the size too.
As a bodge, I've used a diy clamp thing to provide an approximate level of bearing preload, and then just done the pinch bolts up good and tight.
I don't think the big bolt is ever intended to provide resistance to a crank falling off, as the plastic one will fail pretty quick.
