LVB25084 kit was about $244 when I bought it last summer.
Call your dealer sales department and inquire about the kit. (sold different than parts)
In all likelihood they won't have it, but they can search (or you can call around) to find one.
That's how I found it.
-or-
you could order the lever, etc. and buy fittings and plumb it yourself,
but there won't be much savings and will be more messing around
