I have them on my car along with the reproduction lowers and arm rests. I like them and they fit pretty well. I think I tried to buy them from Monte Carlo Depot or something and ended up getting them from another source (it was over 5 years ago) I just go the vinyl ones with the chrome strip and no holes.
They were a lot better than anything I've seen in a junk yard. I've also taken them off and reinstalled them so many times and they haven't had a problem yet.
The lowers had a few more problems with thin plastic near the arm rest but thats not a big deal.
