just a heads up for you.
the front doors have a habbit of opening all by themselves when you are driving along, it all happens in a split second and your reflexes tell you to grab at the door, you will find yourself hanging out of the car as it all happens so quickley, be sure to change your front door locks, or fit some kind of system to secure the doors closed to prevent them from opening whilst driving.
I had a couple of bad experiances whith my drivers door comming open.
the end results are damage to the rear fender and front door, also bending the door pillar, it may never happen to you, but if you plan now and fit something now while you are starting your build, it could save you the pain of having to do these same type of repairs later.
