You'll probably need to let your wheel cylinders in a little. And you may have to take the shoes back off to do this easier. You can put a c-clamp on the cylinder ends. Just snug it for now. Then slowly crack the bleeder screw on the back of the wheel cylinder while tightening the clamp. This would be similar to pushing the piston back in on the front calipers. You don't want to push in too much, so be careful. Once you get it pushed in some, tighten the bleeder screw and take the clamp off. The screw thing at the bottom with the teeth on it is the adjuster. You need to run this all the way in and make your way outward with it, taking the drum on and off a few times checking the fit. You should not have to hammer on the drum to get it on. Not because it needs to be that tight. But because it is hard to get it on straight. Just like tying to get a girl's tight pants off, work one side and then the other. LOL. Hope this helps you out.
