After my last thread on my chernobyled truck electrical system I have been sourcing all my rebuild parts and reading as much as I can on repair and prevention. I found this interesting as it would essentially necessitate the doghead mod for anyone who upgrades to the 28mt. I thought it might be worth bringing attention to this. It doesn't apply in my case as I had 27mt and I own 2 starters I plan to rebuild and I had done the doghead mod.
