Did this on a F2. Works great. Take the auger out amd pop rivit a sheet of high wear poly to extend no more than 12 inches up the sloping sides. Taper the edges with a side grinder (Taper edges before installing) so grain doesn't get hung up on the edges. Did this 5 years ago and no wear on poly. Works best to do this when it is warm as the poly flexes better to install. Good luck
