[V8] timing belts

On my "new" 94, the belt is about 10 years and 76k miles old.  The back of
it has very small cracks like weather checking on tires.  When I checked it,
the belt was very loose on the driver's side cam gear, so much so that I
could have slipped it off if I tried.  Another section of the belt was snug
though.  It made me very uncomfortable with driving it much at all.  I'll be
doing the belt asap.
