Default Factory Strut Tower Part #?

I have a 2008 GP GXP, but the passenger side strut tower was removed (not replaced) by the previous owner.

Does anyone know where I can get the factory one or what the part # is?

Thanks!

Might want to add a pic, really doesn't seem possible unless the car was in a major collision.

Sorry for the confusion. It is one (of two) bars that bolt near the headlight and then to the strut tower area. One crosses over the battery and one crosses over the air box.

These are bolt-on pieces. This is not my car, but you can see them in this pic:

Its a radiator support brace, readily available in any junkyard. Its not exclusive to the GXP either, regular 2004 thru 2008 all models Grand
Prix should be the same as well as some years Impala . Part number is GM 15783983, I would not buy new.

Perfect, I actually found one online (new) for $27 shipped. I don't have any local junk yard within an hour of me. Do you happen to know the bolt part numbers for it? There are 3 of them.

No clue, home depot and bring one from the other side and grab 6 if you need them to match.

They are two different sized bolts, the two in the front are smaller than the one in the rear I believe. I think the front two are 8x1.5mm and the rear one is a 10x1.5mm but I may be wrong.


Also those are the same from 97-08 AFAIK.

The front two were in fact, M8. Here is the part number from O'Reillys:

M8-1.25 x 25mm (x 2)

Dorman number: 455920BP
