Thanks for all the replies and pics. All the manifolds I tried dump right into the Z bar so I decided to go with the Wilwood/McLeod hydraulic clutch conversion. Not a direct bolt in kit, had to make a 35 degree firewall adapter to get the rod to line up with the clutch pedal attachment point. Looks like I'll be using the headers after all. The seller of the kit claimed I would have to cut up my firewall to get the master cylinder to line up with the pedal. I told them I wasn't hacking up my firewall, plus there was no way to mount it where it needed to be as it would run into either the brake master cylinder or the steering column mount at the firewall. They said they were actually made for Ford & Chevy vehicles and they weren't familiar with the kit installed on a Mopar A body and really couldn't give any recommendations on how to get it to work. I'll get a pic tomorrow on how I got it to line up.
