Hotchkis Order - Getting Jerked Around?

[JakeLight]

Put in an order for the RS6 Hotchkis on January 11th and after checking in a week later the vendor they provided an update of 'The Manufacturer Said 2/15/2021' for the ship date. Checked in on status yesterday and now they are saying 'The Manufacturer Said 3/23/2021'.

Is this realistic (a made-to-order part that just takes a while) or am I getting jacked around by a shady vendor? All my other suspension components already arrived by Mid-January that I ordered on the same date.

On that note do I need to wait for the swaybars (is it easier to install while doing other suspension components) or can I move ahead on the other suspension components and just do that whenever it arrives? I wasn't sure if a re-alignment was needed with a change to the swaybar setup as well.
