I think they're all the same part 1988++ ...?
Anyway, I'll let you know in a year or two.
Just put axles from O'Reilly's on mine. About $150 for the pair.
I will say that the "new" ones are a lot easier to put on than the old ones were to get off. The replacement parts came with the inboard flange cut in a semi-hexagon shape so it slips past the lower A-frame without any problem. If the ones I took off were OEM, I wouldn't want to ever have anything to do with those again.
