I would hit the junk yard and get a replacement from another truck. I don't like bottle jacks for jacking cars, too unstable. with a truck it wouldn't have had a scissor jack anyway, but used a crank up bottle "type" jack with a large wide footprint.
A lot of vehicles have a hole in the frame lift points the original screw jack fits into (or similar setup) so a dedicated jack is good to have. For that reason it's easier to place it by sliding it into position from beside the vehicle instead of having to slide under the vehicle to see where to put it like a bottle jack. I keep mine in it's place in the vehicle but when I'm home I use a bottle jack rather than dig out the dedicated one. You just have to be careful where you place it around the lift point.
I bought a car that came without a jack. I bought a cheap bottle jack to carry around, tested it in the driveway with a block of wood. All was fine until I got a flat. Then the bottle jack was too tall to fit under the car... Test your solution with a "flat" tire.
