'70s A Body Axle Assembly 8 3/4 or Other

Looking for an entire assembly as I do not currently have a housing. Intended use is drag racing so a sure grip would be great and a 742 or 489 third member would be preferable in the 8 3/4. Or, if you have a Ford 9" or Dana 60 that is fit to an A Body, let me know. Willing to drive a distance.
