So i bought one of these gauge holders, and i must say its a very nice item, im surprised it wasnt thought of earlier!
Im about half way through the install, which is very simple, basically just need two sided tape. Since im currently going to use it for my wideband, and all the wires for the wideband are already ran, ill need to make the hole in the back a little bigger so i can fit the connectors through, unless I remove the gauge wiring and feed it through from the other end of the wires, but im not going that route. The back of the gauge holder wont visible anyways.
Overall im happy with the product, cant wait to complete the install, Unfortuneatly its cold out and im lazy, so im not going to finish the install for a few days.
