I also used the 911 rubber gauge surround when I installed my originals, BUT if you have 110mm holes (like vs drills), and install 100mm original gauges, you will see significantly more rubber than in Tom's attached photo.
My 2013 VS was delivered with110mm holes ( standard hole for VS), 911 rubber gauge surround ( came standard with car), and repo 105mm Chinese gauges.
Wished I knew then what I know now.... I would have asked for 105mm holes...
I still have the 110mm holes, but I have installed 100mm original '56-57 gauges with 911bubber gauge surround, and a home made 5mm spacer mounted between the gauge and the 911 spacer to ensure a tight fit of gauge in the hole.
attached are some side by side gauge/spacer pictures from my install last winter. Hope this helps...
a) Center- Repo Tach- 105mm, with 911 rubber gauge surround (5mm)- you barely see any rubber beyond the bezel. What looks like rubber is mostly a dark reflection from the chrome bezel. The 911 rubber gauge surround VS uses has about 2.5 mm lip, and fills the gap between the 110mm hole and 105 repo gauge well, hides well under the chrome bezel, which overlaps the dash about 2mm.
Right- Original combi gauge (100mm), with the same 911 rubber gauge surround used with the repo and home made 5mm OD spacer ( black electrical tape). You can see about 2mm of the black 911 rubber gauge surround beyond the chrome bazel once everything is installed.
I didn't like this... So, I color matched and used Westwood rubber metallic paint to paint ( cost of paint and prep material 24$ Directly from Westwood) the black 911 rubber gauge surround.
b) same as above with painted 911 rubber gauge surround...
Rubber paint matches dash metallic paint... And has held up this year with no issues- no pealing. But this is just a band aid....
Looks ok, but I like the cleaner " chrome bezel look with no visible rubber" better. Eventually, I will re-glass and re-drill the dash to accommodate the smaller original gauges, and to hide the rubber. It's in my list of winter project... I'm just not shure which winter yet.... But if I ever need any body work/paint it will get done.
As a reference-
