Yes it should bolt right in
16 or 20 gallon tanks were available on the 1984 c10

yes
Nope.....unless you possibly have a universal trans. The only thing that will bolt to a Chevy trans is a Chevy. The Buick, Olds, Pontiac and Cadillac share the same pattern with each other.

1971 chevy c10
Sure will if they are both small blocks. Never change the bell housing bolt pattern. Im asuming your Chevy c10 probably had a straight six, a three fifty, or a 305. It will be same as a 1992 350, 305, or a 4.3l. Just make sure the flywheel is right for the motor, depending if it is internatly balanced or externaly.
The voltage regulator is inside the alternator.
The years 1983 and 1984 disc brake spindles are interchangeable with a 1982 Chevy C10 pick up.
1971-72 Chevy C10 rear brake drums have a 5+4.75" bolt pattern with a 11" by 2" brake shoes.
