Oh gotcha, I think I saw that post.
In regards to your parts order, does their terms of sale on website say no returns? Maybe call and beg for mercy so they take it back? Maybe offer tio pay for shipping or a re-stock fee if you get desperate.
Otherwise, I don't know what to advice. I bet if you list the part number and it's new in the box , it would sell on ebay for near full price but it may take a long time until someone needs it
As for ordering the right part, did you put your VIN in with toyotapartsdeal? Putting in your VIN with a reliable parts distributor should solve all problems of which part is the proper one for your truck.
Has it been over 30 days? Was it HAZMAT or did it have any fluids in it?
