So next questions now that I have removed all the rivets from my old ramp! (Thanks for the help on that everybody). I've got a rivet gun and can get the majority of the rivets back in place no problem. However what the hell are these that hold the ramp flaps in place? Are these just more rivets that have a flat head? If so can anybody point me in the direction of where I could get hold of them and how to fit them to the ramp? Thanks!
