hey guys just chasing advice on installing a new jettrim matt kit on my 13 superjet. the manufactures instructions say to remove old side matts but say to leave the old matt in the tray on and stick the new one over the top for added comfort. most other installs I have seen say to remove it so just wondering what to do. also as I have never removed or installed matt kits before. when removing the old one from the tray there is the back bumper that it goes under which is pop riveted on do I just cut those out and put new rivets through once the new tray matt is glued in place. any advice would be appreciated as I live in rural qld and don't get to ride with other stand up guys so cant get helpor advice any other way, cheers.
