Hurst competition plus- which one?

[dkpilot]

I am adding the center console to my 69.  I have a Muncie M-21 4 speed.  I know I need the Hurst competition plus shifter with the offset arm so it will not catch on the console shift plate. 

My question is, which one, the round bar or the flat bar arm? I have seen 2 different shift body numbers #2083 and #3128. and some different handle numbers #7236, #7436 (not sure if someone made a typo) and  #7238. 

Will I also need the installation kit for the Muncie trans?

any help is appreciated.
