Rear shocks…., Sorry if covered 100’s of times Options

[Freezin 914]

Recently assembled new rear shocks, Bilsteins.

100# springs, new rubber parts, stock and new lower perches.

I assembled them without springs compressed, and tightened the factory nut assembly (#10 PET) until tight. I believe it is threaded on all the way. Then temporarily slid new rubber bits over the top……my questions are:

My donor shocks had some plastic washers under the hats, do I reuse them?

Do I need any jounce rubber pieces? (Have never seen them used on any of the cars I have parted, or worked on)

Last question, the new nylock nut doesn’t look like it will catch the nylon? Should I use the top nuts I removed from old shocks? I assume the nylon lock nuts would be preferred.

When I replaced my rear shocks with the same Bilsteins, I reused the bump stops and all the hardware etc that were on my old rear shocks. I also installed new rubber isolators in their respective locations. I also placed the circlip on the 5th from the bottom after I inquired about spring perch height to a factory rear shock absorber.
