The '63 bulkhead will have the mirrored cut outs for the pedal towers and steering shaft.
To swap you will need a LH steering box, and the steering relay in the frame has to move over to the other side (rewelding). You'll reroute some brake lines and a few other odds and ends, plus move the e brake handle to the left side if is not there already. I think you'll need to swap the arms on the swivel.
Not a big thing except for the frame mods and locating a LH steering box.
A 63 five door is going to have some problems. Double check the wings and doors in particular as they are pretty much unobtanium.
I guess by "bug eye" you mean headlights in the breakfast. I think most agree that the bug eye term is for trucks post 1969 when the lights moved to the wings (fenders)
