Shims in headlight bucket?

[bishir]

I just installed a set of Hella headlights and I noticed their were what appeared to be shims glued under the headlight buckets. Here is a picture Are these for front end or fender alignments? Seems to be a good idea for GM to leave a few extra...

Thanks,

James

Interesting. Those are the shims used to space the ends of the top plate for the header panel. Dual function!

I usually put a piece of rubber there to stop the bezels from sagging but hey that works!
