the Wal Mart comment is directed at those whom are of the belief that companies like Legendary should have whatever is needed in stock on the shelf waiting...and not willing to pay the price $$$$$ for the seat covers with a limited market. Plenty of threads to show the tight wads. I have worked mopar retail and wholesale in the car dealer & restoration world - the Wal Mart comment is a known phenomena in the aftermarket and is discussed in marketing meetings.
No the masses are not aware of what it takes to re-manufacture seat covers. I have had several tours of Legendary a good while ago now - the owner was very gracious and candid about the cost of development. He is not paying minimum wage to the craftspeople who take 40-50 year old seat covers and make proper patterns and sewing the multiple items together so the new seat covers fit as original.
How many 70-71 sport fury's are left? Remember the 5% rule on non muscle cars.
How many are willing to pay $2000.00 for a full set of seat covers?
If you want Legendary to make covers bring some information and data to the table for the discussion.
They used to make a deal with the person supplying the seat covers - provide the seat covers and you paid much less for the covers. It takes a while to develop seat covers. correct color of material, many of the grains have to be reproduced- that requires molds to be manufactured so the pieces can be run and the grain embossed on specialized expensive equipment. Don't forget the thread type/color, piping colors and and sewing the inserts. A 5 or more needle commercial sewing machine let alone the machines that stitches it all together One set gets built from the patterns and the trial fit begins...sometime the patterns need tweaking, more development. Time = money
