hey awsome build I have a 70 DUSTER that i have wanted to do this for some years now but have been scared to do it cause of no real write up till now. Dont know if this ? was asked but for those like me that have relocated the springs similar to what you did on the front leaf spring birch. can i use that for this setup? AM I ahead of the cam or do i have to start again by making a custom fab birch for those end links. Also would be much appreciated if you could send me the specs cant wait to dive into this one thanks and god bless
