I've searched and can't seem to find an exact yes/no to my question. I met with a gentleman who has a 68 Coupe and put an 8.8 rear from a 90 Fox. He said he is running 02 wheels and still needed to add 1" spacers to make it work. My question is seeing how my 65 Fastback is (correct me if i'm wrong) 2" narrower, couldn't I just put the 8.8 in my car without the spacers? Currently I have an 8" with an open diff and want something stronger with a better ratio when I do T5 swap.

 

then you need 2 inch spacers a side

 

ya know I think the wheel offset may have something to do with the spacer size, but someone here did that swap and modified an explorer rear end and modified the 8.8 axle tubes to center the rear end 3rd member. If I recall it would fit a 65/66 car but the 3rd member is not in the middle of the car.

 

So is a Fox 8.8 "off centered"? Other than swapping the spring perches, i'm hoping to "bolt in" a rear. Am i dreaming?

 

Locate a Granada, Fairmont, Versailles or Monarch in the 1974-1978 range with a 351W engine. They will have a 9" that is a direct bolt-in. ISFAIK, retrofitting an 8.8" axle into an early Mustang will require some modification.

 

I know this is not your question. But you can upgrade center section of 8" and it will be plenty strong. I did that on my 1970 with a 347 stroker and plan on doing on my 66

 

Huey, if you google "8.8 in a 65 mustang" you will find several articles, it's just not that uncommon.

 

I personally don't like that idea, the brakes are goofy and if I recall correctly the ring gears are all poor choices.

 

Thanks coupe, i'll give that a try.

 

I have a Versailles rear if you could use it I am about a hour north of Green Bay, pm if you interested
