Re: Iconic's Charcoal Canister Skid F.S.
The 77740-35531 is for FJs from MY '06~'12.
The 77740-35540 is only for FJs MY '13 and '14 (the years with the air pump on the ezhaust and some other stuff added for increased emissions performance).
The -35540 size is different: (LxWxH)
Maybe Iconic would have to make a longer cover, perhaps? Note, though, that the mounting points did not change so maybe it will fit. Maybe gonna need someone to try it to be sure.
