Long fleetside to long stepside?

[Pancholasvegas]

Hi guys, I am fairly new here and new to the chevy pickup scene.. I have a 1969 C10 Fleetside longbox. I am wondering if it is possible to switch it to a longbed stepside? Would it be as simple as pulling the bedsides off and bolting the new ones on? I know that I will have to play around with the wiring and bumper but other than that is it relatively simple? If it is I would really like to go this route. I love how the steppers look, especially long steppers. Thank you.
