We have a Baja Wilderness Trail WD250U with a bad axle - stripped out.

Our manual says it's part:
WD250U-484 Rear Wheel Axle

But some online manuals say it's part:
WD250U-554 Rear Wheel Axle

But I'm told it's now replaced by part:
AT250U-575

The problem is that the replacement part has spindles (threads) on two sections of the center part of the axle, while the original we pulled off has only one section of spindles (threads) in the center part (just off from center).

We ordered the newer (replacement) part and it doesn't fit at all, and there doesn't seem to be anyone selling the old part WD250-484 anywhere online.

Does anyone know if there are any other rear axles that are compatible with this model? Like - Jianshee, Spam wordSpam word Spam wordSpam word Spam wordSpam word Spam wordSpam word , Mountain Lion? I would like to have a part to cross reference.

Or, if anyone is parting out their Baja WD250U?

Thanks!
