Lookin for a crankshaft..... could use some help

[urdaily3]

I'm in the south Florida area and I'm lookin for a new or used crankshaft for a 2007 MZ3 2.3L motor. It spun a bearing and I'm planning on swapping the motor into my 2004 MZ3 2.0L that has a blown engine.

Any help would be appreciated....... p.m. me for details
