I just tried to put the pizza pans on my Frontier. I thought I was being smart and painted them with Sliver "hammered" finish Rustoleum first. Then I drilled 2 holes in the center cap and used J B weld to glue 1/4 - 20 nylon insert locking nuts on the inside. Used Rubber washers under the heads of the screws to put them on. I thought they came out pretty well.
About a week later I lost the front right pan (and center cap). I'm guessing I might have tightened the screws too much and started to pull the center cap off? I don't know because with the nylon locking feature it's hard to tell when tightening. I couldn't chance it, so I removed the remaining pans.
Anyhow, mark this as a pizza pan fail.
Considering trying to drill the ends of 2 lug nuts and attach there.
