1972 340 switching from auto to manual 4 speed A833. Recommendations for flywheel and bellhousing?

so is your crank a cast or drop forged , auto's in 72 - 74 could have had a cast crank , what does your balancer look like , does it say anything on it . and 130 tooth flywheel with a 10 1/2 dia clutch disc is factory , and 6 bolt crank hub in standard la , only racy cranks had 8 bolts , the early and later hemis both had 8 bolt cranks , but these flywheels will not fit the la car bell housing .
