Are you talking the whole rearend or just using an axle. Either way it wont work because its too wide. You can use the rear disc brakes from the lincoln and ranger 5-lug axles though.
You can use the axels. It just makes the back wheels stick out futher. Some people like it some poeple dont. I think it looks awesome. I'll try to find a post.
I'm not sure however if the rear-end housing will fit in the stock control arm locations.
