[urq] gas pedal weirdness update

Hi Steve, 

Both bushings are the same dimensions, one was semi-rubber (red in color)
and the other foam.  Replacement is both foam unless you go with the VW
neoprene version which is much better IMHO.

The best way to replace these is to actually remove the pedal from the pivot
bracket i.e. remove the two circlips (you can get those off with your
fingers), remove the two pivot bushings (don't drop them behind the carpet
BTDT), remove the pedal.

Remove the throttle cable from the throttle (that way you get ton of slack).

Install the bushing in the pedal and alloy piece in the comfort of your
home/garage etc.  
Than all you need to do is get the cable into the alloy piece (hence the
slack).  Reinstall pedal in the pivot bracket, and reinstall the cable on
the throttle.

Hope this helps.
