Just a quick note... I picked up the Episode IV, V, VI box set on DVD today and I was looking for evidence of this mudflap. There's one shot that illustrates perfectly how one biker had it. It looked like it actually came down about half-way down his arse, not the entire length. I also noticed a few other shots (looking at it frame-by-frame) that seemed to support this half-flap theory.
I feel kinda weird saying this all, since it means I was intentionally looking at some dude's rear-end.
So having said that, would the length be an issue for future Lancer hopefuls? Or is it all about just having the mudflap, period?
