Z Bar ID...Whats correct for E-Body

Does anyone have correct diemensions for the E body Big Block Z Bar. I have a bunch of Z bars but cannot tell whats from what anymore. I am looking to find one that will fit my 70 challenger 440 4 speed.

Thanks,

Steve

I don't have one to take measurements from for you, but I've had good luck identifying parts using the pictures and descriptions on the Brewers website.

Just played this game with a 440 Sixpack install in my 1971 R/T Challenger.

First, you need to determine what size bellhousing you have, 10 1/2" or 11".

The tube length is 9", the difference in the torque shafts is how close the offset arm is welded to the end of the tube.
That determines what adjusting rod you use also.

E-body info at the bottom of the page.
