You DID unbolt the adjuster/retainers, right? Just checking...

Worse come to worse, cut the housing along the axle tube portion to pull the ends and axles out, salvage the chunk, and sell the housing and ends to someone for a narrowed rear kit. It'll be easy to press those bearings and axles out with the ends free from the housing so you should be able to save the axles, too.
