I enjoyed watching this and your methodical process. I, too, and working on this conversion. I'm actually in the planning stages right now. Interestingly, my 2009 mega cab does not have a carrier bearing; however, I would like to have one to mitigate the potential balancing issues, in addition to driveline angles as I lift the truck. I already have the longbed QQ frame and 8ft dually bed. This has given me the opportunity to see the differences/similarities between the frames. I do have the actual frame measurements from collision software. Interested in seeing how you will approach the wiring/fuel/brake lines/e brake extensions as I believe I have decided how I'm going to do it all; just like to see how someone else tackles the same issues. Hoping to work on mine this winter (I'm in Florida)
Another difference I didn’t know about. It makes sense it would run with the longer QQLB driveline without a carrier bearing since the wheel base is exactly the same. Essentially you are just trading two feet of bed space for the mega cab, the difference from the output to the rear diff would be the same. Most of the groups I follow say they cannot make a driveline for the LBMC because it is too long and the balancing issues. Since I will not be lifting much or at all, extending the carrier bearing shaft is an easy option. For what you are talk long about for your truck, I would use a stock carrier bearing driveline and get a longer one made for the rear to keep driveline angles smaller. Love the info!
