Shadow shocks hook right up for the early Magnas.

[MagnaJohnv45]

Hey All,
I have found various pics on the web of magnas sporting shadow shocks. I picked some up from a 83 shadow, there were only about a half inch difference. Does anyone knoe which year shadow had 2 in lower shocks? It must be a later year because 83 85 seem to all be 12 1/2 inches.
Thanks
