All early RV6's were ONLY available with manual flaps, later Van offered the electric option and a retrofit kit. I loved the manual flaps on my -6 so much that I built them into my -7. They are simple and reliable. As others have stated, you need to acquire a -6 weldment for the retrofit. You will also need the internal button and spring parts. No big deal installing this setup, although some fabrication will be required for the latching arm and internal mechanism. You will also need to shorten the actuator arms (hex is way to go), also you can shorten the handle to your liking. Since you mentioned that you are not a "builder", you may want to get some assistance from an RV guy.
