Based on pictures of a 67-69 cluster, it looks like it would fit, but I'd need someone to take a couple measurements off of a cluster to be sure.
I wasn't planning on selling them, it was more about giving something to the community. If you want to take measurements off your cluster PM me and you can confirm for all of us that it will/won't fit on the earlier clusters. You pay shipping and you'll need order pins.
Another member who reached out to me has the pins for sale, so I'm going to name drop him @MoparMike1974 and leave a link to his website.
