The thickness/gauge? I did not really check. It was a scrap piece of flat bar stock about 20" long and was enough to do both sides. It is thicker than the factory steel, but not like tank armor. If it's too thick, then you tend to burn holes in the thinner stuff trying to get it to weld properly.

I actually used plain, used motor oil right out of my oil drain at work. 80% of this used oil came out of a 1999 F-250 with a 7.3L DIT. I put it in a spray bottle and squirted till my hand was sore. The oil was thick and it's easier if you thin it with mineral spirits.

I did not remove or disconnect anything except the tires. I did keep some wet shop rags handy to protect the steering boots and fuel lines on the driver's side. There is a surprising amount of room to work when it's on a hoist.
