Is this for an A body?

Look at the build date for this Buick rear.....it’s so late, is it for our 68-72 GS?

 

Either 342nd day of 1970,for an early 1971 car,or 342nd day of 71,for an early 1972 car.

 

I thought 72 had 3 digit suffix and 71 had 2 digit???
example
LKB 1972
LK 1971

Thought the far right 2 is shift (2nd shift)
B buffalo plant
342 day of year
LK 2.56 ratio OPEN

??? I am sure there are more Buick gurus that will help on this?

I know....it appears to be a very very late build date. No way 72 Buick’s being built in December of 72.....maybe a warranty rear end?

 

The last “2” is the shift,not the year.

 

At the end of the day.....it’s a corporate 10 bolt with bolt in axles, fits an A body......all good.

 

Since the letter B is missing in code, it’s a 72 rear. So it must be 342nd day of 71, 2 nd shift.

Thanks

 

this is info I have

 

Thanks Jim

 

Isn't there an additional Date Code cast in the lower right of the center section?

 

On the front side of the pumpkin,on the passenger side,there is a Julian date.
