Looking for mast step

[SteveSarabande]

A bit of a longshot but here goes. I have existing holes in my mast from a previous owner. I believe they are mast step holes.

I can't find any steps for sale that replicate this hole pattern. The vertical distance is 200mm, the horizontal distance 75mm.

Anyone got any links to steps that would save me drilling more holes?

How expensive would it be to get someone to make 10 of those?
