cant find 8 3/4

I cant find an 8 3/4 rear end anywhere close by!!! So my next guess would be a ford 9"?? Is there anything better then this that dont cost an arm and leg? I would really like to have an 8 3/4 but none of the salvage yards have one. what should I look for? what would fit the best and with less modification in a 72 scamp? thanks
