Rear End Narrowing

I found a 9" rear end out of a 73 Ranchero.
I don't remember the exact dimensions, but it was quite a bit wider than a 65-66 housing. Ended of making the housing about 2" shorter than a 65-66 housing.
I had to do a little grinding on the backing plate, but that was pretty minor.
Then I called up Moser and had them make a set of 31 spine axles to fit the new housing.
Don't forget that your rear rims will need less backspacing than before.

I am just curious why youmade it shorter than the stock length? I thought about doing the same thing with my 8.8 to upgrade axles and make 15" wheel fitment easier.
I have a 66 coupe.
I have an 8.8 (yea yea I know), but it was a good price and is inbetween the 8in and 9 so it can handle what I need.
The problem is the c-clip axles. Not anymore! I found mosers that are able to be shortened and resplined for c clips.
I have a problem, which is why I want to narrow it.
When I take off hard and hit 2nd, I dip and it sounds like the rear tires rub on the fenders, because they stick out a little, and it is chewing my sidewall up (the fender lip that is..)
I want to narrow it to get rid of that, and run 15 or 16 x 10-11
Help? haha.

If the 9" ends that you get have the same mounting pattern for the backing plates that your current rear has, then you can use your current brakes. There are, I think, three different ends you can use. "Small bearing" is what Mustangs have stock. "Big Bearing Torino style" would be my preferred choice. With these, you can use Explorer rear discs easier.

Wheels that wide will require some cutting and welding on a 66. The wheel wells are not big enough.
