I have a 1980 Huffy "Good Vibrations beach cruiser which has been in parts for a little while. I was able to find and put back together everything except I am missing one of the metal cups which are at the top and bottom of the head tube of the frame where the handlebars/fork assembly goes through. This little cup holds the bearings allowing the handlebars to be rotated freely without wobbling so this little piece is somewhat important to make the bike ridable again. I'm not sure of the exact name of this part unfortunately.
Where would I be able to find a replacement for this piece to be able to get my beach cruiser back on the road?
