9.25 van rear end in 1969 a body

I know the feeling. I can find an 8.75, but don't want to spend that much money, just not in the budget. I'll be following along to see if anyone has done it. I've also been pondering a Ford 9" from a Granada if I can find one in the boneyards, or a Ford 8.8 from a Mustang or an Explorer. Ideally I'll find an a body 8.25 sometime to replace the 7.25 in the Duster now.
