Tail gate had spring loaded cables on a reel as seen in Assy Manual and maybe in repair manual. Hard to find original parts for those. Only came on clam shell burbs. The lift gate had metal sliding rails with a click up catch pawl. Your burb is built to accept barn doors if you ever want to switch. You don't need a throttle cable but it is nice to have a choke on dash if you have a manual choke carb. You may have an automatic choke (bimetal or electric), in which case no cable is needed. You may or may not have a pull-off. Don't think you have Fuel Injection? Probably not the way it started in video. It looked like it would start right up with the correct pre start procedure. In the video it was asking for gas! Sounds good with those pipes but sometimes can give you a headache on a long drive if they rumble inside that big sound chamber.

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
