Abody 8 3/4 complete rearend drum to drum

I am looking for a complete drum to drum 8 3/4 rearend for my 1970 Duster. I want a 489 case posi and would prefer a 3:23 ratio in it. May get by with a 3:55. I am located south of Cincinnati, Ohio. let me know if anyone has one. may be able to use just the housing drum to drum if it is complete without the center section and buy that later. I am building this car from ground up. Thanks,Bill
