I have purchased the front and rear fillers ( both @ different times) and at one time they sold just the spoilers ends ( car was in a fender bender and I lost it). The front fillers only took about 3 weeks from the time I ordered it. The rears took a month. I have no idea why they wont just stock 5 pairs or so on the shelf at all times. I think it will increase their reputation and sales immediately. I was also happy with their product as well.
I've ordered the fillers for the fronts and it took one day to the next, they're local to me so I just picked up. The dude did say they were made to order
I have their front and rear glass bumpers and front and rear fillers. Super happy with the quality and they were simple to install. You have to drill out the installation holes but they have the "indent" marks so you know exactly where to drill the hole.
