I would weld a stud or short hex-head bolt to the chassis rather than trust a bolted-only connection not to oxidize/corrode between the bolt/stud and the sheetmetal.
On the avatar car (full-frame) I ran a short length of threaded rod through the floor (with nuts and star washers) and welded a short hex-head bolt to the frame rail. Ran one short cable from battery- to threaded rod and another short cable from the outside of the sheetmetal to the bolt. Welded another bolt to the frame rail in the engine compartment. No starting problems, ever.
It's only 'overkill' until doing it in a less fussy way doesn't let you start the car.
