Would the rear end (8") of a 1968 Cougar fit a 1968 Mustang GT/CS? Any differences?

Thanks!!

The rear end assembly is the same. Meaning the third member, housing, axles, and brakes. Axle perches are in the correct location so it is a direct bolt-in.

The difference is the much longer leaf springs on the Cougar and the Iso clamp rubbers on the leaf springs.


A bit of trivia for you all.

The 5 lug 28 splined axles are all the same length (side for side) from 1967-1970 on all Cougar and Mustangs for both 8 inch and 9 inch rear ends.

Interesting info, CJ....Kewl!

I wonder if the longer leafs on the Cougar was engineered for a softer, more "luxury" ride.

I also wonder if those same springs gave the Cougars a cornering advantage in the '67 Trans Am Races, and why the Mustang team told them to stop beating them...
