4-speed blues

The 4-speed '69 Dart Swinger that I bought has turned into a a swap meet nightmare. I am certain that the shifter, arms and rods are all a mismatch. I know that the chrome lever is wrong, or the basic shifter. How do I know what is correct for the bottom? Does anyone have a picture of of the correct orientation of everything?
Mega and year one have bottom parts, but when comparing, they don't look the same . Don't know which is correct.
