That will bring you to the online catalog. Be aware, some parts that they offer are somewhat pricey. For instance the wheel pants for my fifth scale WACO are listed at $36.00 plus shipping. When you order, you find out that the price is for each piece. The set of two runs me $80.20 to get them to me. I don't know what your parts for the ST-A will run, but I just wanted to advise you of that pricing schedule.
