hey does anyone know if the two tow hook covers on the rear bumper on the 2IS would fit on an IS-F rear bumper?

I measured the 2IS one to be a rounded square to be 2.5 inches by 2.5 inches, but I do not have an IS-F one to compare it with.

 

They have different part numbers, so I'd think probably not. Even the 06-08 and 09-11 ISx50 ones are different. :|
