i read max's 4 link article when he first posted it and built a wishbone 3 link a week later for a friend and instant center is like a foot or so passed the front bumper or around there.. dono if i set the right angles for the driveline and differential but we mounted the link bars and tabs while the leaves were still on to keep it close
turned out good with minimal change
now that i understand angles and stuff like that i shouldnt have any problem building any rear type suspension.. doods a madman
