Triangulated 4 link

[Longstep70]

Im doing this on a 59 Apache, not a 67-72 C10 so the frame is straight and i think its narrower.
I dont want to have too much hanging below the frame because I want to lay pretty much all the way out at full dump. Im setting these renders up at a 5" ride height and so if i setup the lower bar under the frame it has to be able to articulate upwards enough to accomodate the 5" drop and not interfere with the frame; that's why I have been trying to tuck them into the notch front.
I asked about the thickness of your lower bars becasue you recommended making them beefier than the uppers but yours look thinner. I notice the angle of your articulation points is different than the shots of the satchell on the Jag up at the top here. What's the reason there?
