I used to be able to buy from Legendary interiors and get a small discount for my Mopar race business, but not anymore: whiney:
Who else besides them has and or makes decent interior parts for our cars now: help:

Thanks in advance for your help.

Depends on what you need...
Door cards, seat upholstery, etc I prefer Legendary: best quality & accurate colors.
That said, I've always tried to send a color sample just to be sure.
There's also PUI but some of what I've seen of theirs is not as good as Legendary.
For carpet, I prefer ACC.
You can try Dante's - member here - he's a good guy & always straight up with me.
Beyond that is the usual: Classic Ind, YearOne, MegaParts, etc., even Ebay.
About the only A-body stuff I still have is one '70-up bucket seat backrest foam and a pair of rear brake drums.

In my opinion, look for good originals...unless you want to wait. I ordered door cards last year from Legendary and was told it would be 32 weeks. I got them in 21 but that's still a long wait. I bought them from Dante. He seems to be able to get a better price then buying from Legendary direct. Maybe try looking for some original ones on Forabodiesonly.

Here are some door cards I found from PG Classics. I have no experience with the quality of these. Just passing on the info.
