Finally had some spare time that coincided with decent weather to work on a few parts to bring back to the Dodge to get it going. I have a brand new looking intake and exhaust manifold ready to put on. I repaired my electric choke, brazed some threads onto the manifold to hold it in place. I've got pretty much everything to put the brakes back together but I noticed one of the felt washers that go in the metal cup has disintegrated. Anyone have a source or suitable replacement?
