You are spot on Andydodge!
JSabah, you can call Brewers Performance and order the plastic pieces(if needed), the Mopar Muscle cars used them in the "Z" bars well into the 1970's. However, if you have the metal halves, keep those. Don't forget to grease everything up really well when you assemble it.
The clutch torque shaft retainer clips may also be available at Brewers, but I don't know for sure. I fortunately have never lost one, and never needed to search for one. Sorry for not being useful on the last part....
