1973 duster 340 counter or neutral balance

Is it possible to drill the right sized hole into a neutral balance flywheel and use it in my 73 duster with a 340? How do you make what I have (neutral balance flywheel) work?

Yes there is a drawing in the mopar chassis manual. It is drilling a few holes in a specific location. If someone else doesn't post one up, I will try and find it tonight.
