yeah- I saw that and it kinda gave me the idea. I am thinking that since the one I am looking at is only 1 1/2" round-same as dash hole- it may be alot easier to install as a unit-rather than cutting it all up. Its a down the road project.
Difficulty and modifications vary with application. If your original amp gauge is positioned in such a way as is screen is floating, The 2 tiny plastic attach points found inside the SunPro Styleline gauge will not be trust worthy over the long haul.
The SunPro Volts screen was captured inside the can. it coild not apply stress to those weak attach points. Additional support for a larger floating screen is not as difficult as it is time consuming. Have fun.
