Can anyone give me some advice?

I recently purchased a Quicksilver frame-mount fairing for my 2004 Low Rider.

In checking I found that Vetter actually made a mount for this fairing back in 1982 for the FXR and FXRS Dynas.

I know the frames changed since than, but did the area of the frame that the fairing mount would fasten to change? In other words, would this mount from a 1982 - 1983 FXR work on my 2004 Dyna Low Rider?

thanks for your help.
