mounting??

Does any body have any photos on how to mount the seat?? There is only one bar going across frame for mounting. A upside down photo would be great. Thanks.:out::shrug:

i understand that the rupp ss-5 tanks mount how a normal motorcycle tank should mount (by sliding the front part into the rubber gromets). But how does the back of the tank mount to the frame.. I noticed the seat slips into a notch but i dont see anywhere for the tank to bolt to the frame...
