Is 1990 Yamaha warrior ATV parts interchangeable with 2000 warrior parts?

can i replace my 2000 warrior 350 atv rear swing arm and axel sprocket ext with one from a 1990? are they the same parts|||no u cannot and the reason for that is if manufactures made parts that would interchange they would lose money selling replacement parts. that's 1 reason Davidson almost went bankrupt was to many parts were interchangeable
