Looks fine.
I ran my '94 carpet to the car wash (PO was a

). Stuff was like Chia-carpet. Seeds and water would have made for a good yield. Or a Petri-dishrag.
I had already scrubbed them on the deck. Looked good, but left with too much soap. Took them to the car wash for that, and couldn't believe what washed out. You would NOT have known it from new.
Long as your riser section is hole-free, I think I can work with yours there Dom.............
