8 3/4 for a Early A Body

I have a '66 Dart and I've been looking for an early a-body 8 3/4 axle w/ a clutch type suregrip - very hard to find so far!

My question is can I modify other chassis axles to fit my application? Like a b-body or a pickup? I can find these readily and they are a lot more affordable. Any suggestions would be great - I definetly need a rear end upgrade.

Thanks.
