Here goes, I'm trying create a car / go kart vehicle, and I'm working on the suspension. I have 3 groups of objects, two "anchor" objects, and one bar. Is there a way to make so that I can move one anchor object, have the other one stay put, and have the connecting bar move along with it? Here's a picture to help explain:

The suspension will have four arms in the end, and will work similar to this:

If you need me to explain more, I can.

Thanks for any help.
