51" and a shy over an 1/8th from the rolled part of the backing plate.
GN rear backing plate to backing plate and over all
57.5 over all to 58"
Backing plate to backing plate 52.25 -52.50 range depending on how you measure.
You might have a bent backing plate causing the first persons measurement.
axle shaft length is 28 7/16 inch
center pinion cross shaft is .795
So if you add all that together that is how you get your over all width. give or take a 1/16 ish.
Then minus 2.75 from each side for brake width and that is how you get the backing plate to plate.

CAmaro DUDE...
Hey are you going to chop up a GN rear??? Oh man I will trade you a 10 bolt 8.5 direct fit for the GN ... lol. That rear is worth more untouched.
A 4x4 8.5 s-10 rear will also be about the same width as a GN rear too and it is leaf spring perch and 5 lug on 4 3/4" bolt pattern too.
You really should think hard before modifying that GN housing. Just 2 cents more...lol. Jim

Why the heck would you hack up a rare and hard to find GN rear to put in a 1st gen Camaro ??? Rears for that Camaro are a dime a dozen.
I swapped a Ford 9" into my '67 Camaro when I was just a teenager. The 9" came out of a '67 Cougar and was a direct bolt-in. No mods or welding needed. The U-joints fit, the spring perches were dead-on... and even the E-brake cable fit.
For God's sake don't hack up a good 8.5 GN rear.

Since when did S10's have 8.5 rears in them ? All I ever saw under one of those trucks were 7.5 & 7.625 rears.
The fullsize 1500's had 8.5 10-bolt rears under them... but not the little S10 trucks.

71-74 Nova, Omega, Ventura, and Apollo came with an 8.5 rear that bolts right into a first gen Camaro. the only tricky part comes if you've still got the mono leaf springs in your Camaro- if so, then either swap to multi leafs or cut the multi leaf mounts off the axle housing and weld on some "Mopar" spring mounts or your stock mono leaf mounts in their place.
you should be able to buy, modify, and build a Nova 8.5 for what you can sell a GN rear axle housing for.

Yep... I forgot all about those cars... You can steal the front discs, power brake booster, mast cyl and spindles off them too. I grabbed a set off a 74 Omega for my '67 Camaro and they were a simple bolt-on swap.

yeah, look at the bottom of a Nova on a lift and then look at a 67 Camaro on a lift, and you'd be hard pressed to tell the difference. except for the driveshaft, e brake cable, brake and fuel lines, and exhaust, all the parts that bolt under the bottom of the cars interchange.
a first gen Camaro is actually a 68-74 Nova with a shorter wheelbase and smaller trunk.

Later S-10's with the ZR-2 suspension package had 8.5's with rear disc.

i thought the later 2wd S10 Extremes also got an 8.5 with rear disc brakes, too?
but really, it's gotta be much easier to just find a 71-74 Nova rear in the junkyard. look in the factory 350 powered cars.

Hey gottype,
How about trading me for that rear end? I have a 1973 Olds Omega 8.5 rear end with 35,000 miles.
It came out of my Omega. I took it out when I swapped in a 1969 Camaro 12 bolt.http://www.turbobuick.com/forums/img/icons/icon10.gif
I can bring it down with me. I see you're near the Big Thicket. I lived down there.
