1970 duster project
I see now that your rear suspension may be ok since it looks like there
are pivoting sliders on the spring mounts under the rearend. Hard to see
with all of that chrome!
Make sure (on final assembly) that there is plenty of grease on the top
and the bottom of the leaf springs where they contact the sliding plates.
They will have to slide to prevent binding; just pivoting is not enough.
The chrome may be a plus here for smooth operation.
