Ultimate swap confirmation

Hi buddies

I have an appointment with my mechanic to swap my /6 Demon gearbox (3-speed A230 --> 4-speed A833)

Here is what I have :
- The A833 gearbox itself with the Inland gear shift lever and mechanism
- The /6 bell housing with new fork, clutch bearing, sleeve and boot.
- A brand new 10 inches clutch kit.





All others parts : clutch z-bar, 26 teeth driveshaft, rear cross member mount and reverse electrical wiring will be those already on the car and are Mopar 1971 original parts

Am I ready to successfully realize the swap, or did I forget something?

:thankyou:
François
