I’ll add my experience and install for reference. Originally I was going to order directly through Front Runner but shipping was free through Amazon so I went that route. The package was completely intact and had a very thick layer of cardboard to protect the aluminum fairing. Here is the model I went with: https://www.frontrunneroutfitters.com/en/us/land-rover-discovery-lr3-lr4-wind-fairing.html.
I knew I was taking a gamble on the fairing matching up with my Gen 1 Tacoma but decided to give it a try with the return policy they have. The install was pretty simple.
First I cut a piece of 3/4" x 3/4" aluminum angle to match the length of the fairing and attached it to the lower slot with 4 t-nuts on the GFC. Then I placed the fairing on the angle and marked the location of attachment points on the fairing. Then drilled holes in the top of the angle.
Then I installed the fairing
The fairing has a rubber lip that I thought would be great to seal edge, but I forgot about the truck bed moving independently from the cab. On the first test drive it was apparent that I had created an unbearable constant squeaking from the rubber/body interface. First I tried some weather stripping I had sitting around which helped marginally, but if it was cold it was still noisy. After some searching I came up with this felt tape and paint protection tape.
Now it is silent and has made a big difference in reducing the wind noise.
