Anything Else i might need for my conversion?????

Another /6 car going to a v8 and Im just wondering if im forgetting anything!!
My car is a 1973 dart sport, /6, 3 speed column shift, manual brakes, manual steering. I have been gathering the parts to turn it into a v8 car ( small 408 ) with a 4 speed. Ill list everything i have so far and i was wondering if there is anything you guys can see what i might need.

I HAVE:
- the 408
-motor mounts
-rad
- 833 is on order
-have a 8 3/4
- floor hump is in

I know that i need brakes, drive shaft, torsion bars, springs but is there anything else??? Does any wiring have to be changed? will the rear trans cross member work?
