This mod is a bit different in every different instrument panel. Majority of my experience has been in the a-body rally panel. I never got the opportunity to attempt the 67 standard panel you have. I'll tell you this before your sunpro gauge arrives. There are only tiny ears supporting that screen. It wasn't an issue for them since its all captured in their can. With the screen floating in your inst' housing you might consider adding more support. Gravity takes it toll over time. Let us know how it turns out. Good luck
