Looking good! Did you go from a first Gen LS by doing the trunk and all?
Or, was it a second Gen and you just did the bumpers?
The emblems cant be found unless you get the factory grilles and rear surround. You
can get those aftermarket ones from LSK that you can customize. I have a set and I think they are OK. Nothing special and by far from OEM but they look good and unless you are familiar with the OEM ones fairly well ( passers by ) no one can tell at a glimpse.
EDIT: I just remembered, the other day I was just googling and I found this. Look for the number and give these guys a call and see what its all about.
