Ok...My boys (14 & 12) are swapping a 5.9 Magnum (converted to carb) in place of the old LA 318 in their ‘64 Sweptline. Truck has a a833OD with a special Hyd. Clutch Bellhousing and a 143tooth neutral balance Flywheel (Flywheel only has maybe 30 miles on it).

Here’s where it gets tricky....I was hoping to just add a McLeod magnum bolt on balance weight (I bought the weight awhile back) to my current non-McLeod internally balanced flywheel (will have a machine shop place the holes for the bolts)...anyone have a template for where this weight would go?

2nd choice (due to cost)...is there a 143tooth 5.9 magnum balanced flywheel off the shelf that will work for this application? Anyone know if a stock 5.9 magnum flywheel will work? Not sure what size clutch the stock magnums use...but I have brand new 10.5 and 11 clutch setups I can use in the garage.
