GMCpanel,
I almost feel like I am in the middle of "something" here. I was already aware of
the driveline/rearend differences between the two years. I thought the supplement would highlight more differences, ones I was not aware of. As these two years are basically the same, the manual did all it could for me.
I have had excellent dealings with Chevy Duty and am sure, had I wanted to return the book, they would have gladly accepted it..for seven dollars, it hardly seemed worth it.
