Arbor switch ?

[Glacier 0]

Will the arbors from a 48" deck fit a 42" deck ? I have a 42" that is in real good shape but the arbors are shot and the 48" is a little too big for what I need. Any input would be a great help.

If the 42" is a 990501 and the 48" is a 990502 the two outside arbor shafts are the same for each deck 108250. the center arborshafts have different part numbers. The 42" deck center shaft is part number 108252 and the 48" is 108434.
