Ford sells the bolts. Even with a discount(mechanic friend) the lower bolts are like 5-6 dollars a piece and the uca bolts are about 9 dollars. They do come with nuts and loctite.. and I have NO idea why the smaller upper bolts cost more than the longer lowers.

I just swapped my diff about a month ago. Trust me I feel your pain. It was all a breeze except for the four lower control arm bolts. I torched the bushing and then used a BFH and beat the bolts out.

I was able to to get in with a dremel and a small cut-off wheel.
Did the job, good luck.

I did it the easy way. I don't know why I completely forgot to try the bolts that mount the CA to the body. They came right out.
