Big Air Universal Pylon?

Does anyone know anything about "Big Air Universal Pylons"? I sent an email to them with some questions but havent heard back. I wanted to know if the cables that connect to the back of the boat, could be attached to existing cleats on the boat, instead of installing D-rings like they say on their website. Im installing this on my dads boat, and he is not to thrilled with having holes drilled all over the place, incase he ever wants to sell it. I figure the holes that would be drilled on the floor for the base plate would be easy to fix and cover, but not the ones on the gunnel. So if anyone has any input on this, let me know.
