A fellow emailed me last month and told me that the US resto pack is now 50 dollars.
I have no idea if the quality is any better or not.
The free one I received was just black and white copies, which I thought was kind of pointless for the color chips section.
If it is the same packet, it is most definitely not worth 50 dollars.
You can get most information from the shop manuals and the owners manuals(which are in reprints and available from most parts vendors - as well as the old ones for sale online and at swap meets).
Another great source for information is from people who have the old Chevrolet dealer sales and ordering literature from the time period of your vehicle. You ask around on here and people will look stuff up for you. It may take awhile as they are not always online... but they are around.
