tonneau cover

looking to get a tonneau cover for my 94 yota. My bed sides are smoothed and the really the only tonneaus i can find bolt to the lip of the bed rails....anyone know of some tonneaus i could get for my yota??? Thanks

that's what i ordered & it's not TRUELY flush mounted, but it's close. they have you measure the inside of your bed rails & they custom make them to the size you tell them.
good luck

thanks bro
