Finally getting around to putting a carb on my Volvo. Coolant distribution pipe doesn't appear to have ever been removed (all hoses under the intake were marked "Volvo"). Despite using a 3/8 impact gun, one of the bolts snapped off:

5/16" nut fits a 7mm bolt shank perfectly:

Welding blanket for protection (I use flux wire, which throws a lot of sparks. On the plus side it doesn't care about coolant all over the place, or being outside):

Nut welded on:

Broken bolt removed. I just turned it out with a flat wrench. Obviously heat from the welding broke it free:
