Looking for donor rear axles for 65
#13
How long are we talking about? If a month or 2, that's fine. If so, let me know the details: price, gearing, open/limited slip, drums included, shipping... And if you're narrowing, will you be reusing the springs?

My understanding is the 8.8 is supposedly stronger than the 8. While the 9 might be bullet proof, I destroyed one behind a Cleveland years ago so anything has its limits. I'm only looking at 275-300 hp in this setup as a cruiser so brute strength is secondary. I already have one offer for an 8. An others? I'm all for negotiating at the moment. The goofy 50 post rule keeps me out of the classifieds. Hell, 10 posts should eliminate spammers...

From looking around, the Versailles swap is one if the most popular choices for the classic mustangs. With a 72, you need a wider axle tube, so it looks like you need to be searching for a 67-73 Tornino, Ranchero, or Fairlane
I found this on another forum. Hope it helps.

And then BAM! The Cowboy comes up with the goods and then some. Thanks, dude! These are the numbers I need!
BTW, you mention a 72. Just for clarification mine's a 65 but I'll settle for a wider 67-68 in a heartbeat.

No problemo. Sorry, I missed the title stating 65 and looked at your info under your name that states 72 Mustang Fastback. In that case, something in the 58" range like from a 77-81 Granada, Versailles, or Monarch should work. The Versailles and Monarchs will probably have disc brakes axle tubes...bonus!

you can also pick up a '95-up explorer or mountaineer 8.8 rear and shorten one side about 2.5" (to take out the pinion offset) and use a second passenger side axle. you end up with 31 spline axles, a posi, 3.73 gears, and 11.25" disc brakes with parking brake axle that's 56.75" wide for about $350. less if you do the shortening yourself.

Urban Cowboy: Good catch on the 72! I forgot about that in my stats. When I signed on I was Stangless and used an example of what I owned in my first childhood . I'll have to change that when I get the time.

the 9in i have came out of a bronco so i need to narrow it to get it to the right width because its something like 6 or 7 in too wide.
to be honest, try to find another rear end. i would be more than willing to sell you mine if i could even throw a guess out about when that might be but i really cant..
