RE: The 64.5-66 9" housing I built is back from the powder coater!!
here is some unedited info from the web page I am building on the subject
There are several reasons I chose to do this:
1. Having the tapered axle tubing is period correct for a 65-66 Mustang even with a 9" rear end. Of course I only add that because it could be a valid reason, I personally couldn't care less about "period correct" I am putting a Jag IRS unit in my personal Mustang for heavens sake.
2. By using the "period correct" tubing existing u-bolts and mounts can be used so there is no need to source them.
3. Most mustangs came with 8” rear ends so donor housings and axles are easy to find and relatively inexpensive.
4. The 8” axles are 28 spline just like many of the 9” differentials and already the correct length, not to mention that as long as you are not running slicks a 28 spline axle can handle upwards of 400 HP
5. All the other stock components such as brakes mount up with out having to modify anything
5. Most axle tubes from the donor 9" housing have different spring mount location that need to be relocated or all kinds of extra mounts that would need to be cut off to modify the 9”
6. In many cases the O.D. of the 8" tubing is almost the same as the I.D. of the original 9" axle tubing. Making the mod simple.
7. My favorite reason because it is fun
