Brian,
You never cease to amaze me with your knowledge and experience. Walt, you have a good eye for detail. I will amend my previous comments about the brackets. I just took another GOOD look at the silver convertible's brackets, they are different than my other GSs. Yes, this does have the power driver's seat, hence the different bracket. I stand corrected. Can't slip anything by the gurus that inhabit this website.
