If your throttle body hasn't been bored with larger throttle plates installed, the spacer is a total waste of time, money, effort, and enthusiasm.
The reason the "Big Block" throttle bodies got the spacer was because they have bigger throttle plates. The cone of fuel spray has to be wider to reach the edges of the throttle blades, so the injector is lifted up a little. With the smaller throttle plates, lifting the injector results in fuel spray hitting the side of the throttle bore.
What is the pressure rating for a stock spring? 14 lb.?
Buy some screws at a hardware store.
