It's Genuine Access Cover. I know cause the first one didn't fit and dealer hooked me up with factory in South Bend. Access's owner (Terry) dealt directly with me and wnet the next day to a friendly Toyota Dealer and 'fitted' a new top himself. (at my sugestion) He changed the deminsions making it 1" longer and 1/2" narrower and made a new cover to the new deminsions and sent it overnight to me.
Great Service, I will deal with Both Dealer and Access again.
I will tell you Terry said I should consider their "Premium Hard Top Cover". He told me he put it on his Harley F150 about 2 years ago and it's the nuts. So maybe..
