0 JoeH Posted September 7 Share Posted September 7 Go to the Mack EMedia website and search for book 8-211, click View File. Everything you need should be in it. 2 Quote Link to comment Share on other sites More sharing options...
0 JoeH Posted September 7 Share Posted September 7 https://macktrucks.vg-emedia.com/ProductDetail.aspx?ProductId=6302 You can also buy this through your local Mack Dealer, though I had to talk my parts guy through the EMedia website so he could find it to order it. It's a flashdrive, not a DVD. Worth it's weight in gold, has every chassis model from 2000ish to about 2021. 1 Quote Link to comment Share on other sites More sharing options...
