I rebuilt my original rear shock today. Here is a good video from SEA.
https://www.ebay.com/itm/264203465436 And the top shock buffer: https://www.scootermercato.com/Scooter-Parts/Buffer/60536 
Before: OEM 1964 Piaggio rear shock leaking like a sieve.
This is the seal you will need.
De-rusted and a new coat of paint and all new rubbers. It's easy to justify being cheap by saying you want to keep it original!

 . That's great. I like the idea that you opted not to resort to SIP jank, but kept it original.

Here's what I used for my GS shock rebuilds. I did a fair amount of reading saying this is the best, so that's what I got. So far, shocks seem fine with it.

You could use motorcycle fork oil, which is made for the application. You can get various lighter weights, below is an example.

The seal on the rear of the SS has an OD of 32mm and fits differently. Both it and the 20x8x5 seal on the front shock have different types of lips than a normal rotary shaft seal.
The o-ring on the front shock is shot but I think I can match something up.
