Sparta Stingray (Stingray is not an option in the model selections here) frame with the engine mounts re-welded to accept a Puch motor. Lucky for me the A3 bolts right up. Moved the seat, custom tail light, Sachs dash with speedo and kill switch, swapped the headlight and a pile of other changes. I have a set of Tomos mags I'm going to swap out so I can fix the gearing to something reasonable.
