3x BT-20 for BT-60
Perfect for your Astron Ranger or Scrambler recreation. The piece is well-engineered. I used all three rings for a Scrambler: two glued together at the mid-point of the three engine tubes and the third at the top. You need to order three engine hooks, three engine blocks and three 2.75" engine tubes. When you're done, you will not be disappointed.
