55 later rear axle housing questions

[Mike327]

I was wondering if there are any direct bolt up replacements for the OE axle housing that can be scavenged from the junk yard. What make and year doner vehicle? I am going with 5 lug disc in the front and need to either change the rear axle to 5 lug or get a complete housing with upgraded brakes not sure which route to go yet. I know i can have one custom built but trying to avoid the expense. Any help or advice would be great.
