I'm starting this thread to document the process, and itemize all my components in preparation for Colin's visit on June 1.
Thanks Robbie for helping me get this far! So far, I have the following:
My original Dual Solex PDSIT 32-34 Carbs (restored, thanks Tim)

Correct 1973 205J DVDA distributor (Thanks Bil!)



New Plugs (NGK B5ES) and Wires

Air Cleaner, Mounting Brackets, Warm Air Intake ducting "Donut Piece",
