trans out/ inspection pics

[Cutty1]

well since there's no snow and i have the time i pulled the 350 trans out, and since i put in my posi with 3.08 i need to know what driven and drive gears i had and i noticed stress marks or heat cracks? on the inside, dont know much about trans so not sure if there is normal

ohh never mind as i looked at the picture it's part of the die when it formed thought that was cracked... but anyway the driven gear is orange and the drive is yellow and before the posi it had 2.56 rear gears, and now i have 3.08 so what color gears do i need??
