Injector codes?

[Kris K]

So I need to replace one injector on my truck (cyl #1) The injectors on my truck all say BB on the nut on the injector. All I can find are D coded injectors. I found in the tech section it wasn't best to mix injectors, but I really don't want to buy 8 injector. I've call Checker, Autozone and Napa.
