Somewhere in the very rear of my feeble memory I seem to remember obtaining a ratio pumpkin out of a '55, 6-cylinder, 3-spd. I was "souping up" my '55 at the time, with a c. Not exactly a "scream machine" after I did all of this at 16 yrs. IF my memory is correct, and the pumpkin was indeed athat doesn't mean it was original to the wrecked '55 I obtained it from. Just my guess.
Thanks, David. Thanks George, I found it - BB Are the last 4 digits the date? Could it be red oxide? As far as I know, the diff housing was painted red oxide.
I even have a 3 speed out of a '56 that is red oxide and I've rebuilt a 3 speed overdrive that had evidence of red oxide on the outside AND inside.
That's quite possible Tom. The engine in it is a 56, and I just determined the transmission is a The tag is missing off of the diff. Just too weird that the new one would only be a week newer! Is there anything else on the vehicle that is dated that could be original? And it's correct that the early cars only had the center case painted red and NOT the housing itself I've never seen a good explanation as to why.

As I recall, this would be a I find that odd for a 6 cylinder car. I havent cleaned off all the road grime so I dont know the code cast in to the housing. Think this could be a ?To say it was well received would be an understatement.
Some enthusiasts feel the 9-inch is a comparable replacement — and an acceptable swap into a Chevrolet muscle car — but when compared to the 9-inch, the bolt has a definite advantage. The bolt positions the pinion-gear higher on the ring gear, which reduces the load on the pinion. This results in less parasitic loss from the friction caused as the gears mesh. Introduced inthe bolt rearend became a staple for Chevrolet racers. The bolt was introduced to performance buyers in While it was originally designed for use in factory-built performance-rated cars, it was installed in both cars and trucks until AfterGeneral Motors was only installing its bolt rearend in cars, but the bolt remained an option for trucks until When looking at a bolt rearend, it is important to know that bolt axle assemblies use different components for cars and trucks.
This means parts are not interchangeable, which can come back to bite you later if you buy the wrong assembly. For instance, the truck bolt uses a smaller inner pinion-bearing 1. We recently saw this bolt at a swap meet. While it is a bolt, it is from a truck. The owner stated that it was not a Posi-filled rearend, and came with gears he believed to be around 3. Also, the offset for the ring gear is different. Another thing to consider is car axles will not work in a truck housing.
Trucks first started using bolt rearends in the G-series vans and C-series pickups. They were used until the end of production in Blazers from through also used this differential four-wheel-drive Blazers had it installed on the rear only. Early truck bolts had axles with 12 large axle splines. The differential carriers are also narrower than those in passenger-car units.GM differentials come in a wide range of sizes.

If used in a daily driver or cruiser application, the 7. This is an 8. It is internally different from the 8. However, the gears will not interchange with a Chevy 8. The axle shafts are also held in place by four-bolt retainer plates at the outer bearing, not C-clips.

After all, they were plentiful and since they were all parallel leaf spring applications there were only two small brackets to trim off before installing the rearend in the hot rod of your choice.
Measuring about 60 inches from flange to flange, they were a bit wide for early hot rods, which may explain the number of hot rods with some sidewall showing outside the fender in the '60s and '70s.
However that measurement was spot-on for many postwar cars so these rearends were among hot rodders' favorite rear axle swaps. At the time you got modern drum brakes, easy-to-find gear sets, and best of all, a price that was approaching free.Pulling out the Rear End with FIRE - 55 Chevy Gasser
Of course that was 55 years ago, and today things have changed dramatically. The supply of original ' rearends has dried up and those who are found are, well, 55 years old. Pitted housings, non-limited slip, small axles, bearings, and drum brakes that are no longer modern, are all features you can find on a ' Chevrolet rear. As a matter of fact, not only have these rear axles fallen out of favor with early street rods, even the Tri-Five bunch is removing them in favor of a more modern unit.
It's a neat car with ample power and a great look but he wanted to improve the old Chevrolet's street manners. It was time for improved suspension and brakes along with a limited-slip differential to handle the horsepower under the hood and provide better handling through better traction. While the subject of our conversion is a '56 Chevrolet, it should be noted this swap would be very similar on all Chevrolets from and virtually any other car or truck with parallel leaf springs.
And if you are wondering, yes, Strange Engineering also has bolt-in rear axles for later coil spring cars.

To that end, a bulletproof Strange Engineering S60 bolt-in rear axle was ordered, along with performance shock absorbers from Performance Online. The original parallel leaf springs are still the main components of the rear suspension, but we will have superior brakes and shocks improve driveability, along with a gear set that will handle all the horsepower we can throw at it. Back in the day, the bolt rear was king for the GM crowd, but today's modern motors can easily overpower the old bolt.
The S60 incorporates Dana 60 components. The 9. The S60 is equipped with strong spline axles so there is no need to upgrade axles and these rearends are available as complete units with no brackets, ready for your fabrication or there is also a long list of bolt-in housing for most popular cars.
The very cool aluminum rear cover is the crowning touch to a true performance housing. We ordered the bolt-in variety of the Strange S60 with a gear set, this way all the brackets were in place for our '56 Chevrolet installation. Inside we selected the Trac-lock limited-slip option and on each end of those big 3-inch tubes we have drum brakes but several disc brake options are available too. The installation was really very straight forward, being a true bolt-in swap. The only fabrication consisted of making new hard brake lines for the housing; the rest of the project was done with wrenches.
The process is simple enough that just following the photos will show you how easy the swap really is, but always remember the safety side of things when you are working under a car.
Axle housings are heavy so if you are working on a lift remember to put safety supports under the front bumper, and if you are working on jackstands be certain the vehicle cannot move after removing that rear weight. Use proper jacks and supports to raise and lower the housing and be certain the springs are completely unloaded before removing the shackles. Since removing the rear housing involves dropping both leaf springs now would be the perfect time to replace both the front spring-eye bushing and the rear shackle bushings.
We used a set of urethane bushings, U-bolts, and lowering blocks sourced from Performance Online.
