Default 82 Rear Spring Bolts

So I decided to take the wrong rear spring out while rebuilding the trailing arms and the rear two bolts so far have not budged. I've been spraying break free on them and using a 1/2" breaker bar to try and loosen them. The front bolt was not tight and when I tried to tighten it up just to see it feels stripped if it's threaded into the aluminum differential like the rear two.

Thoughts?

Only thought I have is the use of heat to break them loose. You may have to heli-coil the one you removed.

I've been soaking them as best as I could from the top and with the impact gently going loose then tight they finally started to move. So once I get it to move I keep adding break free and going in and out slowly. They are not completely out yet but there's hope now that they move. The front one if it's stripped then a heli-coil is in order.

I got the spring out and the front bolt hole threads are ok, I guess it was just loose.
