Did GM just change the Heritage center? I can't seem to find the free information packets for each year.
Five minutes of searching around their reworked site says that they haven't installed the link to get to the pfd archives. I use those archives every day and have shared links to specific years hundreds of times for the older trucks. I tried to message them and that isn't working either on my computer.
Try this https://web.archive.org/web/20220000000000*/gm heritage center https://web.archive.org/web/2022060...eritage-archive/vehicle-information-kits.html https://web.archive.org/web/2022060...eritage-archive/vehicle-information-kits.html It's kind of hit and miss. I was able to pull up 1913 and 1937 chevy, and 74 nova, others just apparently empty links.
GM's to busy scurrying about trying to go all electric ( that their CEO doesn't understand where the electricity comes from ) to spend any time on something of value !
I hope they get it working again, I really like looking through them, you can find a lot information not found anywhere else.
