Debate on 1969 Z Trim Rings 2nd Design

[69L78]

Attached are pics of what I believe & have confirmed as the 2nd design 15x7 trim ring. A friend of mine purchased these 15x7 trim rings in 1984 along with a set of 15x6 for his 1968 RS/Z that he has owned since 1971, these were purchased from Troutman Chevy in Millersburg, PA. The part # 3901704 you see on the boxes is for 67-68 Z/28, so he must have gotten the boxes mixed up, I think the GM # for these trim rings ends in 696. Can someone post the earliest part # for these & the superseded #"s.
I had these at the recent Solid Lifter Showroom & I was talking with Skip Lecates and showed him these trim rings, he 100% confirmed these are the same trim rings on his Survivor Hugger Orange 1969 Z with 22k org miles with 09D Trim Tag.
