Used Rear Axle Housing

Here is an Ebay auction for a used rear end axle housing by Ebay member "gt35067" with a Buy-It-Now of $2,500.00:

This is an original axle housing from a 1966 K-code Mustang.

This housing is in great shape.

There is no major rust issues.

The housing measures 52-3/8 inch long.

It has the large hex bolt in the back with the L marking. There is also an L paint mark on the inside.

There is some bumpy surface, but most of it appears to be slag specks from welding so it should be real easy to clean up.

The perches have been moved closer together and reinforced. They now measure 37-1/2 from center to center. They will need to be moved back to 43" center to center to be correct for your mustang.

I got this axle housing from an old time racer. He told me this axle originally came from a 1966 Mustang Group II race car. The original car was used as a parts car back in the 70's. I got several pieces from him that he said came from the original race car and his story seemed more real when he handed me a set of 31 spline axle shafts that he said were originally in this housing. 31 spline axles were only used in the Group II race cars.

He also told me the axle perches were moved because he was planning to use the axle in a 1971 Maverick race car he was building back in the mid 70's, but ended up not using it. This axle housing has sat in his shop for the last 40 years.

I will be posting the axle shafts and a few other parts in other auctions.

I did not notice this issue when I first posted this housing as I was in too much of a hurry. This housing is actually NOT an original as the axle tubes where they meet the center section are smaller in diameter by a noticeable amount. Original 65/66 Mustang 9" housings are the same size where the tubes meet the center section. If you used a pair of axle tubes out of an 8" 65/66 Mustang rear end to make up a 9" housing, this housing is what you would get. Therefore it is extremely unlikely that this is an original housing.

Don Quillen (SAVETHESTANGS) on the first version of this forum did make up the correct sized axle tubes and was able to properly duplicate the original 9" axle housings of both types for 65 and 66. They looked really good. I am currently researching as to whether he still does this. Here is a link from the old forum and he has a number of posts there:

Fred you are correct he did make them ,I purchased one from him back then to have as a spare, when placed side by side to an original it is spot on, don't know if he is still doing them.

It is good to hear that you were happy with his work, Chuck.

I have sent emails to both of his known emails from the past. They were not returned as errors so possibly he will get back to me.

When I purchased it I had it shipped to the ford dealership I was working for at the time , because it looked like an NOS housing the parts manager asked me how and which other ford dealer I found it at .

That is very cool!!!

I was planning to bid on this one myself, but after comparing the pictures to a few of the original housings that I currently have, I decided against it.
