Which Sojag Hilo pergola does each Hilo privacy panel fit?

There are two panels, one per side length. The 10 ft panel fits the 10 ft side of the Hilo 10 x 10, 10 x 12 and 10 x 20 ft pergolas and measures 106.7 in. wide by 82.3 in. high assembled. The 12 ft panel is made for the 12 ft side of the Hilo 10 x 12 pergola.

Both fix on through the holes already pre-drilled in the pergola's structure, so there is no drilling to do, and both need the pergola, which is sold separately.
