LA 360 vs. 5.9 Magnum damper weight specs?

So the engine I pulled is out of a 2000 Dodge Ram 1500, I can't use the damper that's on it because it's the one-piece type, the serpentine belt pulley can't be removed to swap the V-belt one on. I was thinking of taking both dampers to my machine shop that balances crankshafts and having them do it but I'm betting that would be at least $50 and at that point I might as well just get a new damper. I guess I could sell my LA damper too if I need the money.
