Auto Meter gauge cups are the perfect solution to your gauge mounting needs. They can be mounted anywhere, and are the perfect addition to a full pillar pod, or cluster. They are designed to work with Auto Meter 52mm gauges, but will work with most other 52mm (2 1/16") applications, however we can not guarantee fitment with other companies gauges. If using other gauges the biggest concern would be depth of the gauges; being too deep is the only way they would not fit into the cup.
