Here is my jacking adapter for my GlaStar. As you can see, it requires that the cut-outs for the other landing gear legs be made. For my trike I block up the tail with a saw horse, slip the adaptor into the taildragger leg hole and jack away. As a bonus the nose wheel will also lift off the ground. Wheel and tire service is a snap with this device. It weighs about 6 ounces and is part of my onboard tool kit.
