I,m leaving mine on the bottom
Had full alignment check and all is ok,no vibrations on road etc
My m8 fitted his on the top,didn't look right,the gap between beam and chassis was massive.
Also look how much of the standard bush sticks out of the top of the beam,also look how much of a Powerflex beam mount sticks out of the top,both the same as the Deflex with the spacer fitted at the bottom
What are the bobbles on the top of the beam mount for if they sit against this spacer????
The bobbles on standard bush sit against chassis
