Z-bar questions with big block

unfortunatly I am unsure what underchassi headers I have on my car. ( they had no part number, and came with my car when I bought it)they look the same as yours though.
but when I put my car together I bought Brewer's BB Z bar and everything worked fine. obviously your Z bar is different than mine. I think I would build my own Mod Z bar next time, but one think I notice is your Z bar arm that goes down is way longer than mine is.

if you scroll down on the link, you can see the Z bar I bought.

I don't think yours goes close enough to the tranny. also do you have a ball stud relocation bracket for the ball stud on your tranny?
