Everything was lost when I bought my project truck. Someone swiped or swapped, it had an era correct jack instead. Fit just as well on the floor as the original, and didn't require a long*&% handle. Nice jack, but the rebuild is original.
My driver had everything when I got it, including the bag. Can't speak for my project truck, but the bag on my driver is under the passenger seat. It's convenient, and probably kinder to the bag, though perhaps more dangerous. That said, cab corners have holes in them
Come to think of it, my driver has a breaker bar with a socket on it too. Better than a lug wrench.
