A Body 4 Spd Z-Bar Help?...

I have recently purchased a z-bar that was supposedly from an A Body 4 speed. It is exactly the same length as the one that I already had that was supposedly out of a /6 car. Does anyone know what the exact length, and where each of the z-bar arms come out to connect? I am working on a basket case Demon and need to find the RIGHT z bar--- I appreciate any help! Also, anyone that has a correct 4 speed z-bar for sale? Thanks~
