I bought an intercooler with H/C piping for my last F150 and a set of wheels for my L all shipped thro Greyhound, saved a bunch in shipping. Just takes longer since they don’t go straight from one location to another.
I've been trying to get one too. Lots of places claim they're In Stock, until you try to order. I asked BedRug if they'd be willing to do a limited production run if we could get a certain number of orders, but no response yet.
Edit: Just heard back. They no longer have the tooling to make them, so no matter how many of us want them, it can’t happen.
