If it only has 2k miles on it that has to be an install error.... Who put it on?
Also if you mark each cam gear and the old belt before you take anything off, then mark the new belt with the same marks all you need to do is match up the marks on the new belt with the corresponding marks on the gears.
As long as you loosen the cam gears before the belt comes off it will work.
YMMV but i have used this method when replacing a few different belts.
If it was me...... there isnt much of that rear cover missing. Just throw a belt on it and call it a day.
