Wanted A-body 8 1/4 or 8 3/4 Rear end complete

Im still in need for a rear end to replace the 7 1/4 in my 73 Valiant, had one lined up until the seller decided to back out... after I waited a month and a half didn't think it would be this hard to find a rear.

Im located in southern CA if anyone has one please let me know.
Thanks
