FrqntFlyer, yes, I meant the tracks indeed! I managed to get the huck rivets out with a bunch of work, it got easier once I got the first couple out.
I punched out the centers of the rivets, cut them in half with a dremmel tool, then pounded them off with a hammer and chisel-like screw driver. I'm pretty small so it required A LOT of pounding.
Sorry for the delay in reply, been busy pounding at rivets!
