Windshield Wiper 68 Charger

[AllMopar]

I am reinstalling both the wiper motor and wiper hardware on my 68 charger and want to know the following:
1) does the wiper motor require a gasket or sealer when mounted to the firewall?

2) does the wiper arm assembly require a gasket or sealer when mount to the body?

Any insight is greatly appreciated.

The wiper motor has a black rubber gasket that seals it to the firewall.

Each wiper pivot requires a seal, a gasket and a piece of strip caulk.

Different vendors sell the kit:
