Those look like they use the studs to attach tho. The right ones go in a hole. I'm not welding the studs on so the first batch looks like they'll work with the factory holes.
No studs... no welding... no drilling... Those were 5/32 pop riveted on using the stock (factory) holes by using a expander (the black looking thing)...
Or... I could also have just drilled another hole for a small flat head sheet metal screw...
