1969 Dodge Charger R/T S/E

Inherited last year after my father's passing. He had it in storage since 1980's and never got around to restoring it. He was a mechanic and a huge Mopar fan. Always said he'd fix it up when he retired but unfortunately passed at the age of 62. Numbers matching, 440 4-speed car. Needs a lot of work, but starting to bring it back to life. Any advice is welcome as I'm completely new to restoration work.
