I bought the kit from Coastal; instructions included were apparently copied from this Toyota document. Hardest part of the installation was taking the tires off (they only say to remove the rears, but unless you've got a close-quarters right-angle drill, plan on taking them all off). That, of course, has the added benefit of learning all about finding the jack, jacking, tire removal, etc., on a flat, dry surface on a sunny day.
