Coverking still has them. I just checked their webpage. The pull down option says:
- 50/50 sport seat, w/ side airbag, for models w/ factory TRD pkg
Where did you read that they won't work with the TRD package? They sure do!
I got the two tone neoprene: black sides with charcoal insert. The colors fit right in, looks awesome! Picked up the truck this week from service, and the mechanic asked me where I got them.
On Coverkings website they are a little overpriced, though. ($500?)
Try here:
Costco.com
and type "coverking" in the search window. It's $165 * 2 = $330 for the full set, and you can return them at any time if you don't like them.
Good luck!
