i just happen to have a standard pro x seat in the garage. i tossed it on to the viper and it will work with 4 mounting holes in the tunnel. it is 2" taller than the viper seat and is a much nicer position, it fits a little goofy around the gas tank, but if the 2 tabs are removed from the seat it should look decent. ill post pics tomorrow. even though its not the shorty, it will give you an idea.
