Those are the same # bulbs used in the 88-98 body style for cargo lamps. I hope if Breen's got some they're designed better than the ones V-LED's sells. I've been real happy with most of their stuff but I bought some 921's from them for my cargo/3rd brake light, and they didn't work out too well. It seems the sockets are so goddam tight (anybody that's changed bulbs in these knows what I mean) that it popped the leads loose inside the LED's, and they shorted out. When they lit up, they practically caught fire.
I had bought them for both the cargo and the brake light functions. Here they are, along with the "way too long" reverse lights I bought. That's not V-LED's fault, I chose them knowing they were really long but hoping I could find a way to make them fit.
