What happened to the original ones?
On our H31 they were cracked
My son sripped them repaired with epoxy, and revarnished.
To keep them from braking again, I bought a used heavy duty Stainless kitchen sink from Habitat Restore for $20 and cut sections out of it to the size and shape of the steps.
Remounted the steps with the additional stainless supports under them, and have had no issues since.
