I'm building a truck for someone that wants the rockers sitting on the floor using a crown Vic front end and a cobra rear. Right now it seems like the lowest I can get it is with the rockers sitting 3" off the ground. Has anyone on here ever done this before? If so do you have any pictures of the frame? I don't have any pictures right now but I will tomorrow.

 

You could either z the frame up front or cut the frame rails around the CV IFS so that it tucks up in the frame for a more lowered stance. Should gain you acouple inches by the notching or a good 5-6" if you z'ed the frame. Almost the same thing can be done out back but even with bags inflated you will be low to the ground so take that Into consideration if driving height is a factor in this build.

 

See this thread. I belive there are a few pics of how in it. Also you can use the search engine top o' this page.

2x on this approach.. notch, box, and gusset the front frame section to raise the CV subframe. Trim the inner fenders to accommodate.

On the rear, consider raising the bed floor to clear the mega C-notch... personally, I think it's crummy engineering to have the C-notches protruding through the bed or creating a humped bed. That's just lazy IMO.
