Default What rear end is this??

The car is a 1962 Chevy Nova, could someone help me with identifying this rear end...I did check the rear end chart based on the numbers on it and that says it's a 3:08 posi, but it does not look like any of the pictures. The others are rear load and this one is a front load, wondering if this is Chevy Nova or something else?
Thanks

I want to say GM 8.2" 1955-1964.
If it has trailing arm brackets it is 58-64.

These are not terribly strong from what I have read, the axles being the weakest link.

Correct me if I am wrong guys.

Sounds about right to me. I know the '57 Chevy used an axlehousing that resembled the late-'60s-early-'70s Ford 8".

I would say it looks like a typical early style 3rd member rear for up to 64'. I must have blown 8-10 of them along with countless axles on my old 57 chevy back then ! LOL they were just weak !

'57's are just like this except the drain is located on the bottom of the pumpkin.

I agree. I had 4.11 gears in my 61 Impala with a similar housing... axles didn't last long behind the Muncie. I used to keep extra axles and bearings ready. I should have just moved on to a 9" but I was young, dumb and poor plus I thought I was saving money. Now everything I build that MIGHT see some abuse gets a 9" or similar proven axle.

Question; are these axle's difficult to change? I want to convert to five lugs on the rear and if I could just swap the axle's that would be great.
Thanks

Any of the big names like Currie, Dutchman, Moser, Strange, Summers or maybe even Superior should be able to make you a pair of shafts for your housing and choice of lug pattern. I believe all of them have "how to measure" diagrams on their websites. Just choose one, then use their instructions. Price should be under $300 per pair for street / strip axles.

Yup.. Back then, we had few choices. I stuck a 57 Pontiac wtih 4.11's.. It was a very heavy unit. and just as strong as a 9" Ford.. it was a bolt in with the exception of the lug pattern which could be redrilled.

Change the entire setup those things blow. I've broke 2 with just a cammed 350/700r4 setup in my 63 impala daily driver. First one had 3.08 gears and second had 3.55. never broke an axle though just stuff in the member.
