i just ordered seat covers for a 73 dart sport [front bench with arm rest] in the original "bright blue" [b5] vynl.
6-8 month lead time, and when you order, you own them. the only thing to discuss when you receive them is if they are the wrong color, or they are damaged somehow in shipping.
as this is not my car, and i am just a parts procurer for the owner, i research parts then make [my] recommendations. the owner has the final say as to what to purchase and what company to purchase from.
if it were my car, i would have one of the trusted local upholstery guys sew up a set of covers. it would be cheaper, faster, and look the same as his original covers.
i suggested this, but it was not to be.
it will be interesting to see if these covers come "antiqued".

Maybe Legendary and the customers should do photo exchanges before any orders are finalized? Customer sends photos or maybe even samples to Legendary and Legendary sends back photos of the materials and pattern and layout of what they are going to use. For my '68 RR with a two-tone green interior at first the got the two-tone wrong with the lighter green in the center of the door and rear panels backwards. Then when I received the bench seat and rear seat covers the originals had a darker green top on both front and rear seats. They said they have never seen this so I sent them photos of the originals and two others I bought at swap meets. Then when the car was sitting waiting for some other things the center of the rear side panels started to un-attach itself from the panel from I assume sun heat. They replaced all of the door and rear panels FOC as the fronts were showing the delamination too but the replacement panels they sent were once again backwards with the lighter green in the middle/center. They were very responsive with making it right and covering (pun) all of the issues but that was back in 2003/2004 don't know how they are now? Have only used Legendary for all of my Mopars and they were always great to work with. Hopefully they will work things out with the OP's issues.

i can't send pictures of the front seat, as i just picked up the correct bench seat [actually, i got the rear seat as well, as i had to take both] and it has black vynl. [the car came with incorrect 80's vealore buckets]
the rear seat is original, and it's the B5 [bright blue] color the build sheet calls for, so i can use it as a guide.
