No other Fords will interchange directly.

Call Moser Engineering (or any other axle specialst) and order the housing/axle package from them and add the parts (3rd member and brakes) from a donor 9" you can get locally.

Oh and you will need a different (shorter I believe) drive shaft too.

I don't have to have a direct boltup. I was looking for one that is the same width and I can fab the brackets. I am going with an alum driveshaft also.

I contacted Moser once about narrowing and adding brackets to my supplied housing in addtion to making a pair of axles and they flattly told me they would not do that and I would have to buy a complete axle housing from them.

I would rather set up 9" carriers than an 8.8. I want to have street gear and track gear set up. It is easier to swap the third member than the whole rearend.

You will need to have the axle tubes shortened to make that fit. I don't know of any direct swaps, but I think that the 66 9 inch rears are a closer fit cause a lot of guys swap an 8.8 into those. Problem is the 66 9 inchers are so expensive you are better off with a currie or something because they only came on K code mustangs.
