Preparing to install a set of Poison Spyder DeFenders (Zero Flare) here in the next week or so. In preparation I went ahead and installed a set of Drake Offroad hood pins. Here's a couple pics. Let me know if you have any questions about the install, but it's pretty straightforward. The instructions that come with the kit are pretty good but they do contain a couple of errors.
Basically, there are two 10mm nuts on the inside of each side of the hood (4 nuts total) holding on the upper latches. Take those off and you can remove the stock upper latches. You then take the upper latches that come with the kit and install them in the same location using the hardware included with the kit (i.e. 2 4mm hex bolts + 10mm locking nut/washer per side (4 hex bolts total)). Don't forget to install the gasket that comes with the kit. Pro tip: The washers go on the inside of the hood.
Then you have to go in each wheel well and remove the single bolt holding the lower latch to the fender. Here's where the instructions start to show errors. The instructions call for a 15mm socket, however the bolt on my '06 was 13mm. Anyway, remove the nut and the whole stock latch comes off. Do this on both sides (2 nuts total).
Next, you have to remove the allen bolt holding the turnbuckle to the latch assembly on the new Drake latches. The instructions in my kit called this a 5mm bolt but I found it to require a larger wrench. I believe it was a 6 or 7mm. When you remove this bolt the turnbuckle and the 2 small bushings will come out. Be careful not to lose the bushings. Take the latch (minus the turnbuckle/bushings) and place a gasket from the kit on each one. Then grab the new 5mm hex bolt from the kit and install this on each side.
Next, it's back under the Jeep to attach the nuts/washers included with the kit (1 per side, 2 total) to hold the latches in place.
Finally, reinstall the turnbuckles in each side by positioning a bushing on the back of the latch (there's a place for it to rest, if you're actually installing them you'll know what I mean), then positioning the turnbuckle and carefully starting to slide the other bushing in place. Get the hex bolt started, and if everything's lined up correctly and you can slide it through both bushings and the turnbuckle. Tighten that hex bolt up.
The last thing to do is close the hood. Insert the pins into the top latch and top of the turnbuckle. Then you just rotate the turnbuckle until the hood is just resting on the factory rubber bumper (or however you want it adjusted). Tighten the two locking nuts on each side, and you're done.
