Canada to USA Shipping hold up Usords???

[XXXGoldL34M20]

Hey guys I have been shipping stuff from Canada to the USA for many years with no problems and great success but recently I mailed a set of 1970 Chevelle Vinyl roof Trim from Ontario Canada to Nevada USA and it is being held at Usords USA.
Mailed it with Expresspost which shows the tracking was to be delivered on March 2nd and I put it in the mail February 25. It has been at Usords since February 27 and it's still there today.

I have never had anything held up for this long and I am starting to worry about the item being shipped. Will it eventually clear customs or is it stuck there for good. Anyone else have this experience?
Hope it goes through as it was an ebay sale that I have $140 into the item and $35 into shipping.
