I'm at the point where it's time to get a dashpad for my 72, and I recall there being mention of the best aftermarket one to get. Unfortunately, I can't remember who had it available.
Use the search function on the site. You will find tons of info on this subject. The two pad options are NPD and OER. You will find difference of opinion on both. Personally I had good luck with the NPD pad. Neither are perfect but the originals weren’t either. Good luck.
I can recommend Just Dashes in Van Nuys CA. They restored the dash pad for my 72 Elky and the results were perfect. I tried several repop products and nothing would fit. Because the pad was the OE pad, it fit perfectly. The job wasn't cheep and it took about 8 weeks, but IMO it was worth it.
If your original pad isn't split or curled too bad you may be able to fix it yourself: http://nastyz28.com/threads/fix-your-curled-dash-for-cheap-money.262859/
Sadly, I have a NOS one that I got about 20 years ago, and it went very bad in storage. I took it to a local interior guy, and he wasn't able to do anything with it. I'm going to pick it up this weekend, and will post a few pictures.
I also have a never installed NOS pad from 20 or so years ago that I had some guy paint the correct color, but the paint flakes off when pressing on the dash. I'm thinking there is a dye instead of paint. Doesn't matter now as I pulled it out of storage and it too is curling like the original dash, so probably best it was never installed.
Even a NOS pad in the box would look bad today. NPD is as good as you can get even though there is some things to complain about it.
