is the 413 axles biger

[5sp. mini]

i picked up a 520 stick my car is a 86 daytona-but motor and trans is 85 so i have small axles but when i got the car motor was out but auto trans was still in car, and the both axles were in the car, so i will only need to change the left-driver side to in stall trans?

You'll need both side axle, 87 and up. You can use the equal length or unequal length setup.
