Folks,
I am not saying that all modifications are a No-No! The original question
was about using Syncro rear shocks in place of the proper non Syncro shocks
due to those shocks being available. My response was to get the correct
ones.  Without making other modifications to compensate using longer shocks
defeats the design of the shock length being the lower suspension limit.
Over the years I have seen the drive shafts get pulled out of the CV joints,
I the drive flanges ripped off the differential shafts, the rear springs
fall out while on the road, etc. The last one though is usually due to the
lower spring perch rusting off or aftermarket springs wearing thorough it.

Not quite the same thing, but similar. I have 930's on my Syncro and put a
modified spring perch on the rears that are heim-jointed, which allow the
trailing arm to travel, without bending the spring longitudinally, it stays
straight while the suspension travels up/down.

Because of an additional ride height of almost 2", I put a Pro Comp shock
that is a 14", stock height is 12". We put the van on a lift and let the
wheels go to full droop and could see that the splines on the axle/CV
interface were too close to "too far", so put limiting straps on.

The end result has been very effective.
