I have a 1996 R1100RT with a stock bmw 33l top case, but it does not have a back rest pad for the rider, pn 46 54 2 317 077. This part is no longer available through BMW. Givi top cases offers a number of different pads that might fit, http://giviusa.com/givi-products/case-accessories/back-rest-pads . Any suggestions for pads that fit or has anyone tried one of these GIVI pads? Thanks, Jim
