No worries, dghii, your post was helpful to refresh our collective memories!
Here's a relevant thread on another forum I remember finding useful:

My only additional tip, is proceed with caution on the rear clip. It found it to be surprisingly fragile. The abs plastic can be repaired, if needed, with abs plumbing pipe solvent-weld cement. (But best to avoid cracking or damage in the first place!) I remember struggling getting that rear clip to line up properly to be properly installed, far more than you would have guessed one should. So, just be careful, and may the Porsche gods be smiling upon you.
