Golf Cart Seat Belts
 

I bought some from Buggies Unlimited, and am trying to figure out how to install.
I have a 2008 Yamaha Gas w/ 4 seats (2 face rear).
Any suggestions on where to attach the posts for the belts? The uprights that hold the seat backs and the roof in place look like they may be weakened with a 1/2 inch hole through them. And the plastic surface of the body looks like it could rip right out.
