The parts numbers for the LS6 & [email protected] engine covers are 12577891 and 12609357, respectively. None of the usual sources list the emblems separately, although I did find one diagram that provided individual identifiers for the emblems on the LS6 cover as well as the insulators that attach the cover to the fuel rail. So I suspect, a dealer may be able to order the emblems separately. I would check with Luke at Lindsay. Finally, used engine covers are occasionally available in the classifieds and/or ebay.
