I can't get my suzuki topcase attached to my suzuki accessory rear rack. I already have the sidecases attached.It requires the small " box " that the topcase "clicks" into and 2 T-shaped protruding bolts ( along w/ a few tiny rubber grommets ). My rack did not come w/ them , and neither did my topcase , and they are not sold seperately. I talked to both my local dealer and Suzuki themself. Both were clueless . Please help.
