Carburetor Identification

[70_440-6Cuda]

Just picked up a stash of parts locally with 2 sets of 6 BBL carbs.  I also pulled mine off as well and going to have them redone.  Hoping to get some feedback here as to whether they are original Mopar or later production. Numbers are as follows and what I understand to be the application.  Would like feedback on if I am correct in my understanding, and if they look to be Mopar or not.  Also if what came off my car seems to be correct based on the dates.  I think the 3rd set is later replacement carbs, but unsure - Thanks!  I know the pictures are hard to view, you have to download them to zoom in and really see the numbers

Off my car, build date June 1970:
4376: 3029 - 1970 center, Auto trans.
4382: 2889 - 1970 Front
4383: 2899 - 1970 Rear

Set 2:
4391: 0879 - 1969 center, Manual trans.
4393: 0929 - 1969 Front
4394: 0939 - 1969 Rear

Set 3:
4670: 1407 (3512835) - 1971 center, Auto trans.
4672: 1468 (3512837) - 1971 Rear
4672: 2835 - 1971 Rear

the dates on the carburetors didn't record the DECADE, so carburetors that have been in production since 1969 could be from another decade (small details/markings on fuel bowls/screw heads have changed over the years, etc.)

but I think you have the gist of it 
early for your car, but a good matched set of probable originals

4376: 3029 (302nd day of 1969,'79,'89,'99,'09 or '19) Wednesday 10/29/69 ?? - 1970 center, Auto trans.
4382: 2889 (288th day of 1969,'79,'89,'99,'09 or '19) Wednesday 10/15/69 ?? - 1970 Front
4383: 2899 (289th day of 1969,'79,'89,'99,'09 or '19) Thursday 10/16/69 ?? - 1970 Rear

@6bblgt anything else to look for other than the numbers?  Going to want to probably sell a set at some point so would be nice to know what I have
