I found a website selling a very nice leather wrap for a Tiburon, but it says it's specifically for an 05. I have an 03 and my steering wheel looks the same as the one on the website, but I don't know if they're the exact same.
Yep as far as i'm aware all wheels are the same fitment wise. Some have red stitching to match the cars with the red leather seats although the majority are black.
Cars fitted with cruise control from the factory have provisions for the multi-function stalk. From what i've seen, models without it just have a plastic blanking cap. Underneath the cap all wheels appear to have the mounting point for the stalk etc. One point to note, there are two different types of clock springs (cruise vs no cruise)... Other than that i'm pretty sure the wheels are the same.
