rear end

what is the stalk rear end of a 71 skylark 350?

 

Should be 8.5, 2.73 non posi.

 

If it is the same as a 70 then:

2 barrel -- 2.56 std.
4 barrel-- 2.73 std.

Performance--3.23

Special order --3.91

Code is stamped on the axle housing drivers side. Decodes listed at www.buickperformance.com

 

My '68 350-2 previously had the 2,56 ... now change for the 3,08 previous owner saw a notable diference . The car isn't a "bomb" yet but that is not so bad .

 

did most or all gs,s come with posi


thanks tony

 

I believe it was an option GS's.
