Anyone know how wide the rear end is on a 65 cutlass I am looking to put a rear end out of a 69 chevelle in my 65 cutlass

 

I put a 70 W-27 rear end in my 64 Cutlass drag car. Just difference in coil perch but will work I did it back in 1973.

 

Hi,

From a Hemming article:

10-bolt axles were also offered in two different overall lengths: 1964-'65 assemblies were 56 1/2-inch, narrower than the 1966 and up units. This extra width was added between the brake backing plate and the lower suspension bracket--if your axle has 1 1/2-inches of space there, you have the later 58 1/2-inch wide axle. This can be important, as the axle-shaft lengths also differ between early and late and do not interchange.

Will a 67 442 rear end fit a 65 442

 

I believe you would have to use the 1967 rear springs when making that swap. There is a difference in the spring pad between the 1964 thru 1966 rear and the 1967 and later.

 

65 is a narrower rear also

 

My experience is that the '64-'65 rears are 1" narrower than the later years. I have put many later model rears in my '65's with no issues.

 

thank you for the information

 

60" drum to drum for the 64 65
61" drum to drum for the 66-72
DO remember - after 50 years now most cars do not even have thier original rears under them so do not assume it...MEASURE the rears before buying no matter what year they come from.
62" for the 73-77 drum to drum (but they will not fit mounting mounts totally different a-body mounting points for the upper and lower control arms. )
