I need to replace the rocker molding on my 99 Trans Am. I called the dealer and he ran my VIN# and informed me that I have the cheaper molding (there are two versions, a $400 and a $1000 one). I have looked all over the net and cannot figure out what the difference is between the two. I will buy used, but can't seem to find the correct one. Can anyone explain to me what the physical difference is between the two??? Pics would be great!

Thanks.

Chris
