I was under my truck a week ago and noticed that the transmission mount no longer had the top nut on it holding it together. I was able to find the bolt laying in the cross member.

I bought a new one and was going to weld the nut to the bolt and mount and was wondering if it just drops right in one piece, or does it come apart to go in?

 

Yes, 1 piece, bolt fits up through the hole:

 

Thanks. Im going to weld the nut to the bolt then the bolt to the mount itself so no way in hell in can twist or vibrate off/out.

Not sure why they dont do this in the first place.

I am sure the one I have on now without the bolt is probably ripped rubber from the mount.
