Truck runs, but only on two cylinders.

That black spacer is kinda necessary, and the fact that most of it's missing means the cap is tilted on the distributor. Therefore cylinders 1 and 2 don't get any spark because the rotor doesn't make contact. Problem is, nobody makes or sells that spacer anywhere.

This is going to be fun....
