CRANKSHAFT REPLACEMENT CHARGER 73 318

[yxkullsgatan]

Hi,

I'm a french owner of 1973 Dodge Charger 318

I'm going to buy a new crankshaft but Rockauto offers the same casting/forging numbers for 3 differents crankshaft, so there's no problem I can order on those 3 crankshafts ? I haven't removed mine yet. Is there a special setting when I'm going to get the new one, to install it in the engine or is it "easy" to replace it, no particular settings ?

Thanks in advance guys.
