Need help assembling a Spining Reel (pics included)

I found a cheap spining reel in a box that I forgot I had. So I bought a pole for it and plan on using it for white perch fishing. I took it apart and can not figure out exactly how it goes back together.

It is a South Bend APT-8PN 3.1:1




So I took it apart to the picture below.



Here are the parts I have to put it back together. *Please use the numbers if you have suggestions so I don't get confused.




This is how I put it back together:

I put number 1. and placed it in the hole. Then I put number 2. inside of the white plastic rim. It seats perfectly. I think this is correct.



Then I took number 5. and put it down gear first and twisted it. I then put number number 3. bracket around it and tighten down screws. *** I'm not sure if this is correct. The metal bracket seems to only hold down the white ring which is number 1.




I put number 4. gear on over the rod.



Next I put number six on. I tighten the nut and then I put in the small screw. There are two different screw openings. Not sure if it makes a difference while hole to use.



Then I put the spool on. I put on the metal washer gear first and then the red flat washer. I know this part is correct.





Last the drag knob. Now I'm done. The spining reel handle turns and it reels in very smooth. But....................this bottom part below is not secure. It pulls apart a couple of inches. I can not figure out how it stays secure and connects to the rest of the reel?????????



I can push it closed. See picture below. But it pulls up with little effort.




Any ideas?
