Hey glad to help and the Pin Stadium thread for support is at the link below.
There is no need to remove anything as they will fit, but on that side you will need to put the Magna-Mount on first and then put the light bar on.
It’s a snug fit and Whitewater is one of the machines that they were designed on as I knew if I built them to fit on that they would clear all others machines.
Here is the link to the official Pin Stadium thread and email me at email@example.com if you need more help. Thanks!!
