RFI - Gauge Sizes

Recommended Posts

I measured the openings in a 2002 instrument cluster housing, and the openings themselves are right at 3 1/2 inches in diameter, with the speedometer (center) opening seeming to be very slightly larger (less than 1/16").  

 

The inner opening on the bezels (retainers that hold the instruments in place) are right at 3 5/16" in diameter.

 

Hope that helps.

I thought you were gonna ask about wheel rim sizes?

My answer is that the Germans were forced into that or Goodyear wouldn't give them a ride in the blimp, since the Hindenburg (sp?) was grounded.

The Americans elected to use metric threads on sparkplugs in hopes some German would show how to brew a good beer, but we are still waiting.

90 mm = .0528852 smoots

 

3 1/2 in. = .052388 smoots
