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.

Just did mine, the same configuration. No, the jounce bumpers aren’t needed, nor the two each side additional rubber rings. Same questions also so took a few days as yes the instructions aren’t clear. They seem to be used on just Boge struts.
Also not clear on the bottom movable rings and orientation of the bottom plate ( lip down).
Be sure to do alignment as change will alter stuff - in my case quite a bit! Nose may be up after springs settle so adjust torsion bar screw.
Ian Karr has a video on the basics.
