The newer aftermarket stock looking 15" wheels are made for the later columns.
https://www.speedwaymotors.com/47-54...ck,405807.html Like a Flaming whatever, or a tilt GM. A much wider back compared to old stock wheels that are made to only cover a 2" wide column.
Mr48 has it right with the gap and mounting that will be visible between late column and old stock wheel.
If you have power steering, get a later 15" stock looking wheel that is wider in the back.
