There is a BIG price difference between 21" A wheels and 21" T wheels. On top of which, the cost of Model T wire wheel hubs if you don't have them, well lets just say, at current market the T hubs will be more then a bit higher then the cost of the adapters. In addition, if there is a problem with the key way or spun bearings with the wire wheel hubs you will not be out as much because you are using the wood wheel hubs with the adapters.
