Z bar is hitting exhaust

I am in the process of assmbling my 70 Mach 1 351C, and I have a problem with the Z bar hitting the exhaust. The car was a 351W and I think I might have a W Z bar.

Where can I get a C Z bar?

Thanks,

Jeff

Problem solved. I had a friend of mine do a little fine tuning on the bar and it worked great.
