WOW you really are the rear end whisper.

I searched a number of times on the internet trying to find the correct words to find that information.


Again a 1000 Thanks.

I love this van...like my 03 Crown Vic after a number of other cars, I worked out the best of all of them.

If you would like to see what all my fuss is about here is a few links:

Here is my main personal face book page: Send me a friend request so you can check all of this out.

First this insane van: There are an number of improvements that are not shown. Larger anti-sway bars, dual batteries under the floor behind the drivers door, a ceiling mounted A/C, converted to Hydro-boost brake system.

On the Fords here is the Mercury before the engine failure. I am moving and improving on all these details to its replacement a 03 Crown Vic P71 ex-cop car.

At the same time you can see what my day job has been.

Using that as a starting point, you can then use a parts website like rockauto.com to compare the length of axleshafts to determine the overall width of other assemblies, too.

It turns out that van rear ends (like yours) are wider than C10 pickup rear ends of the same generation. This was confirmed on the part interchange guides as well. I had assumed that they would be the same as pickup rear ends, but evidently they aren't.

Based on the information above, here are the approximate widths, from wheel mounting surface to wheel mounting surface, of the rear ends in question:

1977-1996 B/D body sedan: 61.7"
1977-1996 B body wagon: 64.7"
1981-1987 C10 truck: 63.7"
G10/20 van: 67.8"

So, you could run a B-body wagon rear end, but if you wanted to keep the same track width you'd need to use 1.5" spacers.



Yes. The carrier breaks for the 8.5" 10-bolt are 2.56 and down, and 2.73 and up.

Nah--I'm just practiced in finding obscure info online. You're welcome.

OMG this is so very complex...The local junk yards have NO codes, other that popping the rear covers off and counting teeth and doing the math...they are totally lost, interchange only.

So once again any chance you might have to codes for to read what the insides of a rear end is?

Nope--those tags are often missing, anyway. They'll have to count teeth, or look for teeth number stampings on the gears.

You'll need to verify too, of course, that it's the rare 8.75" 10/12 bolt hybrid, and not a standard 10-bolt.

Thanks again.

PS Some later model rear ends stamped such numbers into the axle, but I do remember those tags on a nut...

This wish list is getting complex...two questions more, How can I tell a 8.75 from the other rear ends and any idea which make, year and model they came in??

And I came to a deeper question, what parts like these do you still have and are you willing to part with any?

I have been sitting on as many hay stacks I can but so far found no needles.

8.75" has "cut outs" on the sides of the cover. More info here: GM 7.5 VS. GM 8.75 Rearend

I went over that in previous posts. Again, car-part.com is your friend. Search for variants with the "cut-out cover."

At one point I had a set of 8.75" 2.28 gears and carrier. I also had a carrier that would allow you to put 2.41 gears in your factory 8.5" 10-bolt. I sold them a few years ago. I don't have anything else now.

Thanks that make it easier to spot.

As a number of times I am a little too late.

Thanks.
