I mic'd the O.D. of the gauges and they are 2 1/16" and 3 13/16"

So I also talked to a machine shop and they gave me that blank stare which is always telltale. They suggested using holesaws..LOL

So allowing for the dash covering etc I would likely have to go up to a standard size saw..2 1/8 and 3 3/4

I had done a test cut on a piece of similar scrap at work and you are right about slight warp..... also 2 inch was too small... I guess a massage with an air grinder would work..but nah.

The dash is .063" alum H14 3003..pretty soft and easily worked.

I will screw the dash down to a plank. Makes a very clean cut plunging into this backing.

I talked to an upholstery shop and asked about adhesive.They suggested contact cement..you guys have any suggestions there? I thought the summer heat /black dash would raise hell with contact cement ,like gum on hot pavement.

I am pleased with the look of the gauges. I have to get those lucas switches too.
