Technical Is a 56 Corvette rear end the same as a 56 Chevy sedan rear end?

Everything is in the title. Are the rear ends interchangeable?

 

Google has them both at 58.8"

 

IIRC the axles are different lengths for open and posi rear ends.

 

57 was first year posi. Axles are 1/8" shorter.

 

I just learned something!

 

chevy parts book. The housing has a different part number. I didn't look up the rest of the parts, but you can.

I think the difference Jim is that the Corvette housing has brackets on the top opposite the spring pad for a traction type bar.

Cool, I bookmarked that thanks.
Thanks for all the replies.

 

Not in a 56

 

When did it start Scotty? My 62 had them although it was missing the bars.

58 or 59. My 57 doesn’t have them, my 60 did.

 

The early Vettes were built on a 49-54 car frame, so I would not expect the spring perches to be the same as a 55-57 passenger car housing.

 

I seem to remember that the Vette bearing/backing plate housing is slightly rotated where the car is square to the pumpkin.

 

I think trac bar came out in 59

 

There is a 56 Vette rearend for sale on the Detroit CL if you are looking for one.

 

My 58 had the trac bars

 

1959 was the first year of the traction bar in a Corvette.

 

Mark, that would look awesome under there. Did you get it from Guffy or Roy?, it looks familiar...

 

Nuthn neater than old chrome!
