Now available are correct reproductions of the GT door VIN decals. Each of the years available are correct in style, with weights and measures correctly displayed for 72 and 73 year models. You must submit your proof of ownership and we will print your decal for $50.00 shipped in the USA. We are working on the tamper proof die currently, but not available at this time. Paint will show through the Font of the VIN just as factory. What a great detail item for the GT, Kadett, and (Manta up to 71).
After several posts about getting replacement Opel keys for lost ones, or vehicles that did not come with keys, here is a little guide to the mystery of Opel keys. This article will cover the GT model, but in most cases will carry over to the 68-75 model Opels. The GT came with 2 separate keys...
Back to the focus point of this thread, I can't wait for the tamper proof to be sorted out. I'm thinking that would have to happen behind (the sticky side) if you look at the original stickers. The front is still very smooth despite the numerous cuts, which makes me think that the die must cut from the backside to almost all the way through. Like 0.2mm shy of cutting through the sticker. And then they printed on top of this material.
It also makes sense that the die cutting was on the backside. If you're trying to manufacture this material, I could see it happening like this...
1. raw material is cut into desired width, and also tamper proof cut.
2. Cut material now has adhesive applied.
3. Material is cut for the other dimension of the sticker.
4. Any printing is done to the almost finished stickers.
5. For the VIN / build date decal, these are now punched into the finished sticker.
I’m not really focused on those right now, more than likely I will, but I have a laundry list of priorities before making those. There is just not much money in this kind of stuff to spend a whole lot of time
