Yes that are as far as bolting in the rear track width is 60”, but in both years and even up thru 1969 there carrier’s
will only accept certain gear ratios as in. 2.56 to 2.78. 2.93 to 3.23. 3.36 to 4.33. In 68 all the manual transmission cars got the HD 4 pinion Posi with 3.36 to 4.33 gears ( if the car did not have AC )and even the 6 cylinder cars with a manual trans supposedly got the HD 4 pinion rear also . Naturally auto trans cars could have had the HD on special order. In mid 69 the ring gear bolts changed from 3/8” to 7/16”.

Actually 69 is closer to 68 than 67 is.
68-9 used multi leaf springs,staggered shocks 67 used mono leaf 67 also used radius rods(like traction bars) 69 had flat spots on tubes for jounce bushings internals were same as the GTO/LeMans/Tempest

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
