Kelly, they are. I just checked and Pelican Parts has the tray for $11.07 and insert for $6.06. The insert, I think, is the same part as the ones in the door pockets. I think I'll find out what Sunset Porsche wants for the same parts and order them.
My only problem is that any flat deep space in any of my street cars gets filled with screws and assorted small things immediately. On the other hand, I can usually find some spare change there when I need it. Today I've found another $2.12 under the seats while futzing with floor mat straps, complements fo the PO :-)

 

Mike- thanks for doing the legwork on sourcing the parts and prices. I don't have a problem with any loose items in my car cause on my drive to work the car gets thrown sideways a lot. Anything that's loose immediately gets my attention and I make it a point of removing it soon after. I can't stand loose stuff, rattles or creaks from my cars. This Porsche is going to be a real challange in that respect.
