Outer Limits 4x4 Board

I recently had a look at my bull bar and the mounts for spotties an antenna or whatever else floats your boat. But I have a problem.

A previous owner had put something on one of those mounts, you can see the ring shaped wear from it. The problem though is that the one that had something mounted is square, not a circle like the other one.

So now I'm possibly going to be getting spotties, so is this an issue ? and if it is can it be easily corrected ?

Forgot to ask a Sierra specific question. Any good spots to mount an antenna other than the bull bar ?

I was thinking of the right side of the spare at the back was a possible place.

the bull bar holes, try a washer underneath to help that.

try NANE spotties. they are cheap and work good, i have 3 sets and mates also have sets of these.

antenna, i have mounted mine in the end of the guard above the headlight. try above the spare wheel for a spot. need a small bracket.

cheers
