Was hoping to be done today..... but... I was being a little too confident, boy you weren't kidding about that lower hose and the expansion tank!
Lower hose connected to Tstat and lower right of radiator? That should be like eating cake. Or do you mean the lower hose to the tank bracket? We don't call that smaller hose as "lower hose" which is reserved for radiator lower hose.
The whole thing might look easy, but not breaking things and no leak result is the challenge. Don't just try to pull the tank up off the bracket, as it can be hard and break your back, or the bracket. I used a falt screwdriver wedging between the tank bottom and the bracket to separate them.
Don't forget to lube the male part and the o-ring with grease before assemble together.
