I acquired these wheels as part of a two car project package from one of the sons of the owner of now closed Monza Motors in San Francisco. They were new old stock that had been mounted with new Michelin tires. They have 15 miles on them from towing one of the project Alfas to my garage. I dismounted the tires to use on another Alfa.
The wheels dimensions are 14” x 6” with a measured 29mm offset. They have the standard Alfa 4x108mm bolt pattern. Two of the wheels have 1977 manufacturing dates and the other two were made in 1980. There is a barely noticeable visual difference between the 77 wheels and 80 wheels on the inner spoke/flange junction. Sixteen new lug nuts are included along with six used period correct center caps. I'm located in Sonoma (el Verano). You can text me at Four-1-five - 2nine7-fitytwo-88
