are they the same as the originals, they look like those have 4 flat sides on the inner part of wheel. i never really looked at a set of originals that closely to see what the wheel looks like (i have seen the caps)
You are correct, they are not exactly the same.
Full size station wagons, around 1965-68, used a wider 14" wheel that looked very similar if not the same as COPO wheels. I'm not sure of the width or if they fit disc brakes.
Below is a picture of project 1968 138 car with S-10 wheels (I forgot I put S-10 wheels on it, I think it had disc brakes).
