Sunpad cushion. Support board

[massimofinance]

1999 sea ray sun deck 210. I have the front cushions for the sunpad filler (to fill the “hole” in the front of a bow rider) but I think there also needs to be a support board that goes into the groove to properly support the cushions. I’ve looked at the manual but it doesn’t specify anything. I’ve looked to buy it as well and can’t find it. Is it a board or slats? Can I make it myself? Out of what? Thx all.

Check everywhere under all the seats. Usually a folding plastic section.

Done. I don’t have it. I don’t suppose there are the measurements somewhere online?
