May Purchase this 73' duster, need some help!

Darn, so I would have to at least replace the rear axle to get some summer fun out of it eh? I wonder how much that runs, and if I should attempt it with no experience... :d. How does the rest of the vehicle look? Floorpans are not an issue, I'd rip the carpet out anyways at some point so I can do it all at once. :)

He said that he does have a 8 3/4 from a 65 B-body. I wonder how hard it would be for me to replace that...

Of course, I just found this too, for a couple grand more than the green one... o.o zowiee! Just called him and he said that it does not run right now, needs about $1500 in a shop, not sure what that means... he didn't give specifics.:
