If you can get the damper off, maybe replace the front cover gasket and oil seal. If there is a groove on the damper seal surface, get a sleeve to repair it.
The rear main seal can be replaced in the truck, but it's a job. If it's not too wet, leave it for now.

Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
