prior to the pork chop crank the fuji just had reference numbers on the end of the crank stub and mape was wrote on the stub of their crank. no one seems to know who manufactures the pork chop. a recon crank will most likely have the identifiers machined off anyway. you pretty much get what you get in a reman.
If I remember correctly fuji made the pork chop crank then when the 850s came out in 19 mape manufactured the 850 cranks because fuji quite making them and once again there was crankshaft issues.
