I installed a dash cap on my '83 and it turned out great. Of course, I did have my dash out of the car so I was able to clamp all the way around with ~20 clamps. The more clamps the better.
I just read the thread on the dash and it appears that a solution is to put a cap on your exsiting dash after removing it. If one goes this route does it still look factoy or can one tell that you used a cap? Where does one purchase this cap from?
Can one purchase a new one from an after market company? My dash is blue and I want black.
I have seen dash caps from IAP, and you can't tell unless you are right up close. Be sure to follow the installation directions, especially around splits and any uneven edges...
