Anyone know of any company that makes brackets/mounts to lower the upper mounting point of the rear shock absorbers?

I know Terrafirma do this for D1 and Defenders, but not D2's

I have fitted 4" spacers underneath the SLS airbags to achieve a 4" lift for the rear. Now, as I'm using the standard length airbags, I have not altered the spring travel or comppression heights at all.
I have lifted the rear shock absorber mount by 2"'s using the Les Richmond Automotive kit. I would like to retain the standard length shocks as these are matched in their lengths to the SLS airbags. However, in order to still use standard length shocks I would need to space them by another 2"'s. Hence why I'm looking for mounts to lower the top mounting point of the rear shock absorbers by 2".

 

The D2 upper mounts are welded on. You'll have to get +2 shocks.
