My original 66 Style Steel Wheels trim ring has the "lip". So do the reproductions. I looked at the NPD website and they sell a Scott Drake reproduction for 66, 67 and 68, all with the same "lip". I have a set of reproduction 67 Style Steel Wheels on my 66 Hardtop and they do not have the lip.
(I got the 67 ones about 20 years ago because I wanted a wider wheel to accommodate P225/60R14 tires.)
