My 1963 K20 Stepside - Going to be lots of questions ....

[CivilEGR]

Recently I picked up a pretty original 1963 Chevy K20 stepside in pretty good overall condition. My overall plans for the truck are to retain/restore it as much as possible while keeping the original looks.

Highlights:
-Think it was bought for a power company in 1963
-Has a winch that is driven by a PTO connected to the transmission
-Has a power inverter installed in the engine bay
-292 Inline 6
-4 on the floor (not sure what model)
-Transfer Case (not sure what model)
-Closed knuckle Dana 44 front end
-Eaton rear end
-Some sort of aftermarket wheel lock. Will post more data on this later to figure out what it is and how it works.
-Original glass all around, but will need a new windshield at some point
-Mirrors aren't original, but I like them



I do have some immediate questions as I've never owned a vehicle this old and I want to make sure I keep it in good running condition.

-Should I be running ethanol free gas with the carburetor?
-Do I need any additives for the fuel?
-Where are the grease points for the drive train?
-Do I need a special oil with more additives?
