Maybe:

4 x for attaching the stainless steel vertical stationary strips to the glass (on the 4 sliding windows or on the 4 stationary windows, depending on the year of your Suburban).

4 for attaching the small stainless steel clips used to move the sliding window (if your Suburban has the vertical strips on the stationary windows)

Where do you need 8 whiskers?

Post some pictures and that might help clarifying what is needed, and where it is needed?
