What are the differences between the Yamaha Kodiak 400 and the 450 transmission gears?

Hey guys iv kinda gotten myself into a pickle here and hopefully someone that really knows about these kodiaks will chim in please. Anyways whats going on is iv got a Kodiak 450 that was stuck in gear when i bought the bike. Stuck in gear meaning that the transmission was locked up. The motor still ran good it just wouldnt move. So i pulled the engine and split the case and found that 3 gears had teeth broken off of them. And might i add, the metal that these gears are made of is complete trash! Well at least the metal that my original gears are made of are but the gear-set that i ordered the metal looks to be made of a completely different material. Not sure if this is the correct word for it but i wanna say "Pot metal" is what im thinking iv heard that be called before it has like air bubbles throughout the whole thing it looks like. Anyways my issue is that the gearset that i ordered looks almost identical all except 2 of the gears the ones that the chain goes on which drives the output shaft that runs the middle drive gear so i found a chain thats supposed to be for a kodiak 400 since those are what gears i bought that didnt come with the chain. I was just assuming that the good chain that i had was going to fit the new gears. Does anyone know anything about the transmissions in these bikes that wouldnt mind helping me out? The 400 chain should be here in the next couple days when i get it ill let yall know if it ended up fitting the gears i have or not
