A Mighty Vac tool is very useful for not only operating vacuum advance, but has many other uses on these trucks (testing hvac components, cruise control,even bleeding brakes). Good luck
I work at a Caterpillar and Cummins dealer and our parts availability is hit or miss as well. Lots of stuff is USA sourced, but come from states that are shutdown. I don't think this is going to improve until people get back to work...
Chris, if that's a factory bracket and is readily available, I may notch the rear outboard fastener boss a little bit at a time while trial fitting the valve cover. Then maybe fab some type brace connecting to the forward most header bolt. Good luck
If you look closer, you will notice the fan I placed to enhance the dry time of the floor coating I put down. Have no worry's, beer fridge already has a designated spot!
