One of the Arbors can not be connected due to a hole has obstacle where I have to file it down/remove the particle inside of the hole to fit.  Also, beside the items, the FEDEX driver who delivered the Arbors was driving fast for the downhill driveway by hitting a lot of branches of pear tress.  You should mention about it to FEDEX.  Or, have them contact me at 703-945-2083.  Thanks
