Upper Ball Joints

Can you tack weld them in to make sure they don't come out while keeping a wet rag on the joint to keep it cool??
Yea, I'd prefer not to have to tack weld them. We'll see what happens when I get there.

Just got the bushings pressed back in, starting to come back together.

Question:

I took out the cam bolts with the nuts on the outside. Is that how they are supposed to be? Tried to find it in the manual but no luck so far.
