I just lowered it with the existing head. all you need is two tail blade washers, longer m3 screws, and links.
I found the links on an old RC car that work pretty well, but there are others online that will work great.
Put the jesus bolt through the top hole on the block, which lowers the head about an inch. Then put the tail blade washers onto the head for spacing, one small washer for the inner race to ride on and secure it with a long m3 bolt. Don't use teh shiny ones they stretch, get hardened m3 bolts.
As for the link you can get the synergy ones suggested, tehy are a tad short, but work, or devinchi makes some perfect ones for it.
