First I must stress safety. SAFETY GLASSES to be more specific. I had one of those little retaining springs shoot out while trying to put it in and all I felt was my hair move as it whizzed past my head. Then it ricochet off the ceiling and I lost track of it. Damn thing bout chased me out the shop before it came to rest. I did have my birth control goggles on though.
While we're on the subject of those little retaining springs: There are many opinions about what shape, how many, where they go, etc. etc. The ones you see in these photos are from WW. They are all the same and I use seven per side. Seems to work just fine. If you have different springs by all means use them. The principle is still the same.
These are the parts you will need.
Putting the assembly in your lap for this next step works quite well because it can be a bit of a wrestling match to get these springs in.
Hope this helps someone. Good luck.
