what bell and headers are you running?

I've got a 440 in my 74 Duster with a 11" bell from a 69 Roadrunner, and Schumacher headers. I had to move the zbar back because of where the headers dump. All clutch linkages (including the zbar) had to be customized in order to work with this setup.
It's ok now that its done, but it was a major pain making everything work.:angry7:
