A833 shifter issues

I have a 72 340 duster with an 833 4 speed I bought an aluminum f body od and put in it with my original hurst shifter and now all my shift rods are about an inch short, all of them, is there a slight difference with the f body tail shaft? Is the shifter mounting plate different on an A body than an F body is there a different set of rods I can use? Any help or suggestions would be great
