Start at the rearmost end of those bars.  I think there's a cotter on each or something like that, then twist and wiggle each bar to remove from the front anchor point.  Easy to do, two minutes per side.  I had to do this when rebuilding my steering rack.

 I've already salvaged the radiator out of my 82 diesel because it appears
to have been recently replaced. I got the spare tire carriers out of the
way with an angle grinder because I couldn't figure out how to get those
carrier bars clear of the bottom of the radiator, at least without stopping
to ponder the problem.

But one of these days I will be replacing the radiator in my 83, and of
course I won't be resorting to an angle grinder to remove the bars. How is
that normally done?

Thanks,

Jim
