Factory wheel block?

car musttahad a manual trans? I used to keep a block like that in my trunk, but eventually, I emptied my trunk to save weight and bought a CAA membership. Eventually, I gave up the card too, as I almost never get flats; and when I do, I am within walking distance of home. Since 1984, I mightahad two/maybe three flats. My Hotrod had a flat in maybe 2002 or thereabouts. Three miles from home. I hitchhiked home and got a spare. then hitchhiked back. Total downtime was maybe 30 minutes.
