The Stovebolt Site Forums The Shop Area Driveline Size of Copper Washers used to seal wheel cylinder blocks

Hello,

I have what I hope is a quick question. Does anyone know the size of the copper washers used to seal the hollow bolt and block for the rear brakes on a '47 3100?

I know I could measure mine when I remove them, but it'd be nice to have them ready before I start the job.

Thanks,

Bill
