"TMS Component Pack" sounds familiar. I remember that TMS (TurboPower Software, or maybe another company) has software development tools. The number "9020" might be a version number or a specific product code. The user is asking for the "full source", which probably means the complete source code of this component pack. They want the "best" one, which could imply the highest quality, most up-to-date version, or maybe the most comprehensive.
