A couple of questions about the forks

[nutz4spd]

I pulled the forks off the other day so I can install new seals and change out the fork oil. In the process I've noticed something seems off. The first leg I took apart had (from bottom to top) a cupped washer, the fork seal, a flat metal ring, and then the snap ring. The other side had the seal, the cupped washer, and then the snap ring. From what I see in the parts diagrams the correct order would be the cupped washer, seal, and then the retaining ring. No where does it show another flat spacer or washer on top of the seal and then the snap ring. So which is correct? Is there supposed to be another thin washer on top of the seal?

I'm also installing new fork springs and need to add some spacers for those. Is there any harm in using nylon spacers or should I stick to something metal?

PCV pipe is a popular spacer for fork springs.

Some photos showing the parts in question would be helpful.

I figured out one leg was missing the flat spacer that sits above the seal. I ordered one off of eBay.
