8 1/4 Differential desperately wanted

Still looking for an 8 1/4 rear end for my 73 valiant. I really prefer to have one before I start my project and do not want to "just run with the 7 1/4" for a while or until it breaks. I've been reading countless threads that they are absolute garbage and have destroyed themselves with regular use. The rear end is holding up my project plans. I do not want to have to convert a newer rear to fit an A body.

From what I can tell by measuring 56 in from end drum to drum.
Not worried about gearing since I can change them out.
Im located in CA but if someone is willing to ship I can pay if the total is right.

Im still hoping someone has one laying around there not using.

Thanks
