Question about triangulated 4 link in shoebox ford

I've been researching a few posts on the Gambino 4 link installs and I have a question about the top two bars. I noticed some installs have the top bars mounted on the front of the rearend housing as apposed to the top of the rearend. I read this was done to save room in the floor for the backseat. Would mounting them on the front only serve to locate the rearend side to side? Would mounting them on the top locate the rearend plus eliminate twist as the bottom bars do? If I mounted them to the front of the rearend instead of the top wouldn't it be easier to just run a panhard bar instead of the two upper bars? In other words just have a two link and panhard. I'm just asking because I'm learning and I wouldn't think mounting the top two bars on the front of the rearend would do anything for twist and only to locate the rear side to side. Any help or thoughts?

 

You're correct, mounting the top two bars to the front part of the housing would allow some twist. Basically, the rearend could rotate a few degrees both direction (or more if you put a lot of hp to it) and not have to change the effective "length" of the top bars much... by distorting the bushings or whatever gives.

Using just the bottom two bars with only a panhard would allow the rearend to wrap up your bars like cute little fruit roll-ups.

 

Thanks 8flat, I meant just running a 2 link setup with it solid to rearend and the pivot on the frame, say out of box tubing or such with a panhard bar. I didn't think running the bars on the front would do much for twist under load.

 

Ahhhh. 'Bones look good that way, especially with lightening holes....
