the best way to do it is to mark out where you want the rivets. pulled aluminum rivets generally. they are 1/8 so the gold color cleco's are used. once you get all your holes drilled. by the way you drill the plexi a size bigger than the rivet. you take the drill also and take the very outer end or edge of the drill and hit that on a grinder so it doesn't grab the plexi and crack it. once that is done you mark the outside edges with a scripy and than take everything off and cut the plexi. the sabre saw is one of those electric up and down small blade things. make sure and put some tape over the window so you don't end up scratching things up. that's it.
