eek I ordered the wrong tub

I order a 6' tub to fit a 6' framed space. The only problem is that by the time the walls are rocked the space will only be 5'10". I got the shipment stopped when the tub was getting loaded on the truck and replaced it with the same tub 5'8" long. The tub was ordered from Van Dyke Restorers, which turned out to be Cabela's. I wonder if we can get it in Mossy Oak.
