Lol. Almost rid of the snow here but lake is still covered in ice. I haven’t had a look at how Moomba does it but I do know that on the Mastercraft racks you only have to replace the spreader bar to change from a board rack to ski rack. As far as the upper mounting points go. I would think that those gold plated Roswells should be a direct bolt on to their tower. It might be worth a call to them to see what they recommend and try asking for a break on the price while you’re at it. The great one, Wayne Gretzky, once said, “you miss 100% of the shots you don’t take”. Cheers
