If you're an experienced fabricator, any Ford 8.8" or 9" will work. The trick is to get the control arm mounting brackets positioned correctly. If they're not spot-on, you will be breaking other parts. The other concern is warping the housing from welding heat, resulting in eating bearings.
If you have no experience doing this, I strongly urge you to purchase an 8.8" or 9" housing from one of the professional shops and fill it with your choice of pieces.
