I'm making a custom gauge pod for this model and need the overall dimensions. Are the screws that come out of the back removable? I want to make it as short as possible so my depth from the bezel ring to the end is crucial. Thanks

Asked by: Boosters4444
Thank you for your question. This gauge fits in a 2-1/16" hole. It has an OD of 2-1/4". The length from the back of the bezel to the back of the gauge casing is 1-1/2". The brass mounting studs extend an additional 1-1/8". They are solely for mounting and do not extend internally in the gauge so they can be removed or shortened as necessary. If you do modify the mounting studs, keep in mind our mounting bracket and mounting nuts may no longer hold the gauge in a panel.

Will this work on my 06 mustang gt 4.6 with nitrous ?

Asked by: Danny57
Hi Danny, thank you for the question. Our Nitrous Pressure gauges are universal and will connect to the solenoid or directly to the bottle. The 4774 mounts into a 2-1/16" hole and will also fit in various mounting cups as well as any direct fit '06 Mustang gauge pod.
