3 LINK REAR SETUP

No leaf springs left and to.import them will totally kill.my wallet. It's easier to get steel.cut and bent and welded here at the engineers I use.

So maybe the 4 link is right. No need for the panhard or watts link then.
I've always been cautious about the dreaded idea of "bind".
The art Morrison one is definitely the way to go. But...4 link?
