Yeah, unfortunately, Toyota decided to make the '05 Limited look very similar to the SR5. The silver roof racks are gone for '05 unless you get a Sport Edition.
And the silver running boards are gone no matter which model you get.
You could always buy the silver roof rack and bolt it in place of the regular black rack... but that would probably be very expensive.
Would you consider a Sport instead? You'd get the silver roof rack and the silver accents on the bumpers. Plus the hood scoop and the best wheel design.
