PO1 or PO2 on a 1971?

[714Speed]

Hey guys, I want to get a nice set of fin wheel covers for my 1971. Should I be looking for PO1's or PO2's? Anyone have a picture you can share of the correct style? Many thanks. Neil Hegwood

Nobody responded? Huh.
You want PO2's. PO1's were 1968 only. I'm not sure a photo would illustrate the subtle differences between the two, or even differentiate adequately between the Monte Carlo versions
