Help me ID these grommets and washers

[HAFROD]

Guys, since I tore down my 78 Salon in 2008, I don't remember where these parts go. Some or all could be off of a different year of G body cause I do have a tub full of small stuff. #1 and #2 are rubber grommets and pretty sure they go in the firewall but don't remember to what. The others are washer/disks. HELP

#3 is the seals on the inner door handles. #2 looks to be the speedometer cable to firewall seal.

The size of #3 is smaller than the door handle foam rings. I've got those somewhere. What else can they be?
