Rancher 350 parts fit fourtrax 300?

I bought a 1997 fourtrax 300, my brother in law has a 2002 rancher 350. The motor is blown on his bike and he’s willing to part it out. Now my bike needs brake parts, a-arms and other various parts. I was wonder if his parts would retro to my bike, or if it’s just completely different. Maybe swap his shocks for mine? Idk I haven’t looked at his bike yet and I can’t find much online about it. Any info is appreciated!!!
