I have searched the forum and can't find an answer to this. Are the later (90 and up) oval-bushing rear suspension brackets a direct bolt-on to an earlier round-bushing car?

I have an 85 New Yorker with the hollow rear bar axle and found a complete rear suspension off a Spirit R/T, including the brackets and I am wondering if it will bolt right on. I know that mixing and matching the axles and bushings/brackets is no bueno, but are the mounting holes and bracket locations the same between the earlier and later rear suspensions, and will the wheels be in the same location if the entire thing does bolt on?

Thanks in advance for the help!
