once the subframe is mounted, bolt on the tail and everything else, including the front seat. you'll probably have to trim the seat to make it fit snug on the rear of the tank. i usually pull off the upholstery, and use my handy-dandy electric carving knife (like, for turkeys) to trim the foam, and reupholster it. the SRAD tank is quite a bit wider at that point than a later gsxr, so it'll probably need some foam cut out to fit the tank nice and clean like.

never know though, it might fit ok, i'm just picky with details like that. i hate seeing gaps where there shouldn't be gaps.
