I just installed a black cap from Classic Industries on my 79' T/A. I already had the dash pulled, so the cap went on pretty easily. Upon reinstalling the dash though, I found that the cap did stick up about 1/8-1/6 of an inch higher than the original dash. This means that it can BARELY be seen when standing outside of the car. The cap is much harder than the original dash, but it is very nice. You will need to buy more adhesive. They give you about 1/10 as much as you will need. My dash has been in the car for about a month now, but the cap has been on for more than three times that. Its still looking great.
