Just to give you some ideas.
The top was choped 3" but the windshield was not choped, it was lowered into the cowl.
My doors were also rusted out so I cut them flat at the botom hinge and removed around 3" from the botom of the body.
I also chanelled the frame and moved the rear axle back...
Here is my project that Im working on, this is an older pic and the chop is a photochop but I have choped it 3" and Im welding it back up now, it also has been chaneled.
