Both cuda have 323 gears. One is 741 case and one is 489 case. I was hoping to be able to buy a 355 pumpkin and be able to use it for both the 741 and 489.
from everything I know any fully assembled case 741 , 742, 489 will fit your any 8 3/4 housing and axles. (watch center axle spacer if you have / dont have green bearings.)
