I had a mixed experience installing this dash pad in my 68. Overall it's nice quality, looks good, and seems like it will last. But I had to do a fair bit of work to modify it to make it fit properly.
Firstly, there was no cutout for the dash-mounted VIN plate. That's forgivable since it's a '68 only thing. Secondly, the front lip (nearest the windshield) is supposed to have U-shaped cutouts for the screws that attach the metal trim there. I had to mock up the pad in the car and carefully locate & mark where each screw hole is, then remove the pad again and cut a "U" around those marks. Thirdly, the thick flanges on the "face" of the pad didn't allow the A/C vents or plastic dash bezel pieces to install correctly, so I had to trim those away completely.
Lastly, the pad is thicker than original, and I'm finding that the lower / outer edges slightly bump into the door panels with the doors closed (more so on the passenger side in my case). This makes the door a little harder to close, which isn't ideal. Maybe over time the constant pressure will reshape it and it will improve.
It also has a bit of an upward "bow" when installed, so I'm going to have to try laying a weighted board over it for a while to flatten it out.
Another note - the holes in the speaker grille area aren't really holes. They look fine but they are blocked off by material and you can't see through them. So if you plan on using a dash speaker, you may want to spend some time carefully clearing material out of the "holes". Good luck with that.
All these issues aside, it's a nice looking pad with correct texture, and it seems well constructed. It can be a bit of a pain doing all these modifications to make it work, but once installed it really spruces up the interior. It's a lot better than a warped, cracked 50 year old piece, so I still recommend it.
