Gauge Help

I need to replace a gauge in my boat. When I looked under the dash it is very tight and not easy to get to from the back. Is there a trick to pull it through the front without having to do anything on the backside. Any help will be appreciated. The boat is a centurion t5

You need to access the two bolts in back holding the support "U" to the gauge. You might be able to pull the entire gauge panel.
