? about 360 crankshaft.

Well here is the deal. 360 truck motor. bad bearing damaged crank. just want to clean everything and pop an different crank and bearings in there but don't want to take everything to a machine shop to have it rebalanced. people been doing it for years just not sure if the magnum and LA crank counter weights are the same.
FWI the rods on the magnum are narrower at the small end for the piston.
