WANTED: 4.10 Dana for 1970 V Code 'Cuda - June 1970 or Earlier

[anlauto]

Thanks all!!  I am continuing to search and network - thought I had one lined up through a contact here and the deal was almost done, but turned out it was a 3.54 so the search continues - thanks to all for the info and referrals.  Debating on going with something like this if I cannot hunt down an original - any feedback?

You know you can change the gear ratio easy enough right ?

Was the 3:54 a dated 70 piece.

I'm looking for the correct date 70 3:54 ratio. 

I have an October 70 4:10 dana but my car is a 3:54. 
Not looking to sale the dana, but looking for the correct one for my car.
Once I find the correct one for my car, this dana would be on the market.

Pm me details if available.

Yes, I understand I can change the gears, but if I am going to spend big money for a Dana, I want the correct date code and BOM for my application.  My car was scheduled for June '70 build with A32 - Super Performance Axle Package.  If I can't locate a date correct 4.10 housing, I will end up putting in a non dated "aftermarket" Dana.
