I need some information regarding concrete vibrators. Does the head and
shaft come in one piece, or two? Are there places where one can have longer

I'd say that is a very personal decision that the user should decide
if a longer shaft is needed. I'd think though, that concrete would
chafe and possibly irritate the inner linings. Be sure to lubricate
it well.
