IIRC, full Saleen builds have their build number painted on the bumper by the left headlight. While easily faked for a knockoff, I love the look. You can't see it in these photos, but I think its there if you look at other from Mecum.
My favorite Saleen detail.

Yup. Here's one from a different car:
In the process of googling this, I found out there were some Saleen notchbacks...and now I really want one of those!!!
In reply to slowbird :
Those notchbacks are über rare.
Interesting that the one I listed doesn't have the number under the headlight. When doing my research I also found a quick blurb on the same car on the Saleen Owner's club, but they don't mention anything about it not having its number.
In reply to Jordan Rimpela :
Interesting indeed. I wonder if they are prone to peeling/flaking off, as I have seen a few sources for reproduction decals.
