Sigh... So I just spent $1150 getting my gauges done at North Hollywood. They came out beautiful.. But... I sent all 5 gauges, but the left two for oil, temp, etc were from a 70+ early car. They already had the extra bits I wanted- real measurements, etc. So, I get them out of the box and realize in an instant.. they don't have screw posts on the rear for my dash like the others do... I pulled out the old two gauges and they of course do have them. These gauges are exactly the same size but came with a huge rubber o-ring around the outside. That's not going to fit in my 69 dash, right? I mean, at some point Porsche realized what a pain it was to get those gauges in and out and went to this compression o-ring style- so did they also widen the diameter of the hole? Or should they fit with the big O-rings? Sure seems like it's about 2-4 mm too small to fit in there.
So if that's the case, what would you do? I thought about drilling a hole in the gauge, cut a long metric screw's head off and using it like a threaded rod. Then I will get shavings all in my new high dollar gauges
Cant believe I never checked the fitment of these two before I had them redone.
