I looked in my '07 workshop manual and it says there are two floor console finish panel screws, Part Number W505004 and two floor console screws, Part Number W707628. The manual also lists two floor console nuts, Part Number W711098. From the pictorial, it appears that these nuts are used with the finish panel screws.
Maybe you can Google and find the sizes based on the part numbers. Good luck.
You will probably find the bag--after you buy the replacements!
