You need to create a 'phantom' part that is connected to one body with a
hinge (no stops, ie a free-spinning axle); then connect it to your other
part with a slider.
The only drawback to this approach is that you can't make the middle part
massless, though the mass can be quite small (keep an eye out for
instabilities if it gets too low though)
