Here's a recent find.
As with virtually EVERY FSJ out there with a luggage rack (mine is an 88 JGW), the rubber WellNuts fall apart over time and need to be replaced (unless you like rain INSIDE your FSJ). No big surprise, the dealer wanted (hold on to your hats)... $3.60 PER WELLNUT!
I laughed (the guys at my dealership parts counter are getting used to that) and walked out.
The good news is I found the EXACT Well Nut replacement at ACE Hardware (I'm in Texas, but I'm pretty sure they're nationwide). This is a 1/4" WellNut. Bring a sample along with you if you can. They had the 1/4" in two lengths, you want the 5/8" (If I'm remembering correctly). The part will be stamped on the bottom "WELLNUT 1/4 S 109".
And best of all, they were .60 a piece ($3 less than the dealer! yahoo!).
