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

.675" O.D.

They have several sizes in the help isle at Advance Auto and the other places. Usually 4 to a box. Take on with you, stop at Chick-fil-A and cool down. Then stop at Advance on the way home.  Time for a hot dog yet....or chicken? | | | | | Joined: Mar 2012 Posts: 240 'Bolter | | 'Bolter Joined: Mar 2012 Posts: 240 | Thanks Yuma.
