Thank you for your question, MAUREEN! 9178T-AR-DST and 9178T-SP-DST are the same faucet, but with different finishes. AR is a finish code for Arctic Stainless, and SP is the finish code for Spotshield Brushed Nickle. The 9678T-DST is the bar/prep version of the 9178T-DST. It has the same design as 9178T-DST, but has a shorter height. Certain retailers such as Lowes and Home Depot, have Delta products manufactured exclusively for those retailers. We can not guarantee if a specific retailer has an item in stock. If you need further assistance, feel free to contact us directly.
Best Regards, Benjamin
