1G stock Exhaust nuts size?

[AlaskanDsm]

I was going to put on my downpipe after installing my engine yesterday and I could NOT find the downpipe to 02 housing nuts. I would figure they are 1.25 thread like the rest of the car. but what metric size are they? I am at work and not near my car at the moment, and I need to find them. Did a search on the site here and couldn't find it. so any info would be VERY VERY appreiciated. Car is almost ready to start!!! TIA!

i belive that they are M12 with a 1.25 thread pitch.
