Not solved. My Macbook Pro is neither a Core 2 Duo model nor is it a 15" model. But I would be happy to pay $40 for the right ribbon cable, with or without the upper case.

As I mention in my subject line, I have a 1st generation Macbook Pro 17". That is 2.16gz, "Core Duo."

Thanks for looking anyways...

EDIT: The products look the same, but I wouldn't want to purchase something that wouldn't work. Do you know if they are the same cable? Maybe the item number change signifies a change in components in the keyboard/trackpad but not the ribbon? I'd need to know this for sure. I will call the local store Monday about this. Hopefully it will work! If so, a great many thanks to you!
