4 link quick question

[fpjr0]

I have been reading a bunch, and seems like the more I read, the more I learn, but also sadly the more I change my goal , now it seems I know what I want to do, but if I want to do a 4 link set up on the rear, now I have read that with a air-over leaf you need to move/relocate the axle a little towards the rear to keep it from trying to go into the transmission when lowering, how do you accomplish that with a 4 link? just read a lot on 4 links but nowhere I saw about the axle relocation. thanks in advance,,,

p.s. moderator should control the number of post some of us read or we will never finish our projects
