keep in mind that not all toploaders are created equal... there are at least three different tail shaft lengths, which move the shifter position. I believe, and someone more knowledgeable than me can chime in here with a correction if this is off base, that the 289 cars used the longest version of the T-10, which is the same length as the toploader for the full-sized cars like the Galaxie - the longest toploader. If you had a Mustang or Fairlane tranny, that could be your issue... the shifter position would be different. Just a thought.
