Cab construction question (elec. ground)

[IdahoMan]

The cab is grounded via a braided cable to the engine and to the vehicle frame (the pickup box is also grounded to the frame).

This seem like a silly question, but how is it grounded to the frame? With the bolt that holds the cab to the frame? If so, isn't there a rust risk? (I'm a rust paranoid)

Back then ground was achieved by shooting a bolt (with a star washer) through the paint, attaching the braided cable. You can imagine how that works out long term...

These days we use a copper weld stud attached to the sheet metal, which allows for an unpainted surface for continuity but without the corrosion concerns.
