Apparently, the ribs on the Kahuna and the K1 are made of different materials, and the "cheaper" materials used on the kahuna ribs won't take to drilling (as is required to install the K1 knee braces). The individual mentioned they are thinking about offering the ribs in the more expensive material, but gave no indicator as to time frame... The Kahuna ribs are Polycarbonate plastic and the more expensive FC boats use High Density Polyethylene ( HDPE). The easiest solution is to make your own replacement rib of HDPE. Just use the Kahuna rib ( number 2) as a pattern and trace it onto HDPE with a permanent marker and use a 5/8" forstner bit to drill the holes. Drilling and cutting HDPE can be done with standard wood bits and blades. It's easier to work with than plywood. Many plastic retailers sell HDPE and often they have scraps they will sell you. 1/2" works fine. If you can't find HDPE locally, buy a large HDPE kitchen cutting board. Though the Kahuna uses polycarbonate plastic, I priced it against an equal size sheet of HDPE and it cost 3 times as much. Another interesting fact about the Kahuna is it's use of 6063 aluminum tubing vs 6061 for the " more expensive" FC's) 6063-T832 has nearly the same tensile ( 40,000psi) and yield strength as 6061-T6, and more importantly is rated higher in corrosion resistance.
