They have changed their website. I can no longer find the info and the specs etc on how the cars were built. The rpo codes, measurements, engine specs, all that has disappeared. Does anyone have a link to that info?
I discovered that last week and discovered this link via the wayback site. Meanwhile I am downloading all of the years I'm interested in case it becomes unavailable again.
Thanks for the heads up on site page. I was messaging back and forth with someone at GM for 1/2 hour trying to explain what was missing from web address. They had no clue. I knew if I came here someone would know what was going on. Thanks Oldskydog for the info.
