Cool. The part numbers are a little different on the 98 vs. the 2000, but after
98 they changed the wiring harness on the back and went to a plug/socket style
instead of the locknuts. I am pretty certain that will account for the
different part numbers. I doubt they changed the brackets midway in the
production cycle and then went back, so I should be OK.
