So you’re saying all those GM Powertrain plant links and manufacturing data are bogus?
cause you told us in #15:
“35 years ago ~ from that time onward about all they manufactured were the body shells for several cars and three types of SUV”
Even then, the part's manufacturing is of greater importance than the assembly ~ and what you are giving out are assembly statistics. That's just a shell of the real activity of basic manufacturing parts which can be taking place in Korea, Japan, China, India, MExico ~ and you'd never know it.
