Hello, new to the site here, just got a black '03 GT

There's couple of things that im trying to figure out - one - is there a fairly simple way to adjust the clutch pedal to sit lower (its about 2" closer than brake pedal right now), i'm 6'5" and my knee is against the steering wheel every time i shift, and clutch itself engages somewhere right about in the middle of its travel so i assume it would be safe to adjust it lower and still have it disengage all the way. I tried lifting the pedal as the manual suggested, but it doesn't lift any farther than it is right now (maybe im missing the adjustment thing or something)...

And other thing - i have some weird noise coming from the rear at about 75mph or more, sounds kinda mechanical, but changes on bumps, is it likely to be from the axle itself, or brakes, or wind noise, or anything else it could be?

Thanks in advance for any input.
