The info I got from my parts guy at the dealership was that there was only one vendor making these kits. He guessed that FCA wasn't planning on them being as popular as they became and the vendor couldn't keep up with ordered cars and aftersale kits, so all the production was going to cars on the assembly line. I was told they were available when I ordered my kit, and was given a 2 week delivery date. Well that date came and went multiple times. I finally gave up.
