front brake issues

[Vanspeed]

My front brakes would hardly work on the front so I took them apart. Shoes were almost gone, so I sent them out to snyders to get re-lined. Tracks were very nice, as well as everything else. I put everything back together and I can't get the drums to go back on. I adjusted the top nut so that the top of the shoes are in as far as they will go. What is the problem here?
