Finally got around to getting Space Shuttle up and running. It has only been sitting around for about 2 years. I am hoping someone is in the middle of a restoration or cleaning. I am looking for the lengths of the three posts that hold the ramp assembly into place. I am missing one. Please let me know the length of all three posts and its location. Top left, top right and bottom right. Please provide the length of the post from contacting the underside of the ramp to the top of the playfield. Thanks.
