This distributor came out of the 1954 235 Engine in my Chevy car. It's in good shape. I don't know if the vacuum advance works, I would guess that it does not. I believe the distributor fits many years and 6 cylinder engines from around 1940-1962. However, check your application to be sure. On the Delco remy plate inside the distributor, it is stamped 1112396-4E10.
