Dear Welder Series – triangulated upper bar location

Dear Welder Series…
I am researching the install of your Triangulated Four Link on a 57 Pontiac. Do the rear mounts of the upper bars need to be on top of the axle tube? I noticed, even in the pictures of some installs on this site, that some rear upper bar mounts are on the FRONT of the axle tube. Is there a problem mounting them in front of the tube. I am not sure, in my case, I have the room to mount them on top without cutting up the floor.

Your input would be greatly appreciated.

Dear Writer…
Putting the upper bars on top of the axle tubes gives better leverage advantage than on the front of the tube. The bars can also be longer than with the front mounting position. A downside is that the bar will mount 2 – 3″ higher than with the front-of tube position and this can cause floor interference.
