Without seeing the actual parts, hard to understand the problem...
I have a 70 RR and had an alignment issue with the clutch rod pushing the fork. I took my Z-bar over to our local Mopar guru, who then pulled out (3) different Z-bars all of the same width so they would all mount the same.. The difference was the location of the tab for connecting to the clutch rod. The proper Z-bar had the tab closest to the engine side so then the rod would push straight back to the fork not at an angle...

I have had the RR for 17 years but sometime in its previous life someone had swapped out the Z-bar installing the wrong one.

Just my $0.02...
