Axle Help!

Okay so I currently stacking parts and getting ready to FW Radius arm SAS my 94 Explorer Sport. I have a 78 cast wedge hp44 and all the fixins ready to put in it. But just came across a 77 welded wedge hp44. Should I buy the 77 and sell the 78? or should I just say it's not worth the extra work and just roll with what I got?

I would use the older housing. Much easier to deal with and you can put your radius arms wherever you want. Older housing, no question.
