5.9 magnum automatic crank

If it's not drilled for the bushing, you may have to cut some off the tip of the input shaft, I am not sure. I know in some cases with the older stuff you had to. OR have the crank drilled of course.
Can the crank be drilled by hand while its still in the vehicle? Or does the crank need to be removed and machined and all that? If the engine has to be tore down to have it machined I would just replace the crank with a manual transmission crankshaft kit like I did my la 360. Then I'd have new bearings and wouldn't have to worry about that.
