Like said, have installed 4 or 5 in our third gens and they
were all universals, Checkers, Autozone, ect, and one from
GM. The one from GM even had the correct Part# and had
to fab up a bracket.(Universal).
Had to turn ant housing a little. Thats why bracket change
if remember rite. F Body braces from 82-90 or 92 pretty
sure all the same.
One hours work after tire and shield removal and you don't have to be a fabricator to do it.
Splicing the wires took longer than making the bracket.
Clean and oil the ant every so often, common problem.
Just my limited experience with them
