• Open hood of the Miata and support the hood with the factory prop rod. The Hood Lift Strut will install on the RIGHT side of the engine compartment as seen from IN FRONT of the car. Assemble toggle bolt assemblies by firmly screwing the two 10mm headed bolts into the toggle plate provided, as shown in figure A. Install one of the ball-studs with it's lock nut on the hood bracket with a 13mm wrench, as shown in figure A.

• Install one of the toggle bolts into lower hole of the hood bracket with the nut and lock washer loosely on the threads. Now install the hood bracket on the hood (note that the tab pointing down is to the center of the hood). Turn the toggle bolt length wise and insert it in the third hole (counting from the bottom) on the inner hood support. Once inserted, turn the threaded shaft of the toggle bolt so that the toggle plate turns 90 degrees sideways in the slotted hole. Allow the toggle to slide up and down the slotted hole and tighten the nut with your fingers only, you will retighten it later in the installation.
• Before you install the top toggle bolt, insert a rag or a few paper towels into the slotted hole just below the one the lower Toggle is in. This way should you drop the top toggle bolt it will land on your rag rather than fall to the bottom of the inner hood support!
• Install the upper toggle bolt into the slotted hole above the hood bracket by turning it lengthwise. Then turn the shaft of the bolt so that the toggle plate turns 90 degrees sideways. Pull the toggle bolt to the bottom of the slotted hole and hold it there with either your finger or a screwdriver blade. While holding the toggle bolt in place, slide the hood bracket up and pass the threaded shaft of the toggle through the upper hole in the hood bracket and install the lock washer and nut. Tighten this nut and the lower one with 10mm wrench.
• Assemble the firewall bracket by installing the ball-stud and lock nut with a 13mm wrench in the smaller hole on the bracket. See figure B. On all Miata’s except early 1989/90 1.6 liter cars, there is a hole on the upper right corner of the firewall as seen from the FRONT of the car. On early cars without this hole, it will be necessary to drill a 7/16’ hole located 1/2’down and 3-7/8"from the side on the inside of the firewall. This hole appears just above the master cylinder, and below the rubber seal on left hand drive cars. Install the firewall bracket using the short 17mm headed bolt through the bracket and into the firewall hole. Lift the bracket so that its top edge is hard against the upper edge of the firewall. On the back side install the large diameter support washer and lock nut using 17mm wrenches.

• 6. Finally snap the lower socket of the strut on to the firewall bracket ball-stud. Using two hands slightly compress the length of the strut and quickly snap the upper socket on to the hood bracket ball-stud. (This will take some effort, as the strut will want to extend to its maximum length)

• With the Hood lift Strut installed, you will find that when you first open the hood, there will be some slight resistance as you raise it the first few inches and then it will gently rise open on it’s own.
