Are the new parts from the Making History DLC available in career mode? I am having a difficult time finding a straight answer on this, and I would like to know before I purchase it. Thanks.

Yes.  They're part of the tech tree, just like the stock game's parts.

Furthermore, if you bring a (stock) save forward from 1.3.0 (at least) to 1.4.1/MH, the new parts get inserted into the existing tree and parts bins.
