Taps only come in two different hole spacing and your will be one of them. Our coach is on its forth galley tap. The original needed repair and no parts were available (35yo at the time). I bought a replacement and then found out that it would vibrate open and DW didn't like it at all. We bought one she thought we would like only to find out later that we couldn't fill a corn/lobster pot under it. The next we could, but it didn't have a rinser included as DW felt it would be a water waster. This current does and fits all the other things as well.
Choose wisely.
