Default Auto > 5spd Swap?!

I'm sure it's been gone over but I searched this forum to no avail.

Just going over everything I need, or things that need to be done in order to do this properly.

Pedal Assembly - Have it
Master cylinder - Have it
Slave cylinder - Have it
Flywheel - Have it
Clutch assembly - Have it
Transmission - Don't have it
Trans crossmember - Don't have it - Or can I use the auto one?
Driveshaft - Don't have it - Or can I use the auto one?


What am I missing? Anything on the motor that needs to be swapped out in reference to anything such as wiring for example?

Out of curiosity is the rear end gear a lower gear with the Auto's? If so does anyone know what that ratio is?

^^^ I'm aware that it's independent. However coming from RX-7s, their Autos had 3.90 rears instead of 4.10 on the M/T

Independent meaning its the same for both transmissions

and you have alot of options if you want to change it.
