How fancy and how much do do you want to spend?
Carlo Leoncini has 450 cranks with rods.
He is a very nice fellow.

Thanks Graeme,
That is an awesome site and resource. The only problem is that the crankshaft costs more than the whole bike!
My shaft has stripped threads and local machine shops etc... are afraid to weld on it due to it being hardened steel.
I am looking for one in good shape and not too fancy. This is my first rebuild so inexperience and expense are a delicate balance! Thanks for the help,
Richard

I had my 450 scrambler crank done at Syd's Cycles in St. Petersburg FL. I paid about $1000 for them to rebuild the crank with a new rod assembly. The rod assembly is about $600. Malcolme is the guy you need to talk to. He has been racing and working on Ducs his entire life. They can probly fix the threads on your crank as well. He quoted me a min of $250 if all they had to do was press apart the crank and replace the bearing. So if your rod is good, ( sorry it probly isn't) it shouldn't cost you that much. If you pick up a used crank it will need rebuilt and will likely cost you $300 or more so i would ask Malcolme how much to fix yours first.

a 350 widecase crank has the same 75 mm stroke as a 450 crank .
if you would rebalance the 350 crank to 450 specs it works perfect in a 450 .
my 0.02 cents

Thanks everyone, the ebay looks like the teeth are worn pretty bad.
I will check out the other suggestions too.
Still looking in case anyone runs across anything!
